I have a newly built pond that is located on some property that will be my future house site. Unfortunately, there is no electricity run to the property yet so electric aerators are out of the question for now. Has anyone had any experience with using solar aeration systems? Do they work as well as electric? The one that I am considering is made by Malibu Water and costs around $750.00. I know Solar Bee makes a system, but is initially more costly than I would like to spend, and probably much bigger than I would need. My pond is 1/3 acre and 8' deep. Thanks in advance for any comments or suggestions.
L bream, I can tell you how to buy and set up for a little more than 1/2 that. I looked at the Malibu deal, it doesn't tell about the compressor. You are in no hurry, as it is a new pond and not stocked(correct?) Look into the specs of the pump and post it. I can tell you how long it will run. It is best to have a deep cycle battery instead of running the pump directly from the solar panels.
Find out if AC or DC pump, how much current it draws, and how deep it will operate(how many cfm @ what psi). It looks like it is advertised mainly for de-icing.
You should be able to wait for electrical, but if you are dead set on solar, collect the above info and post or send me a PM.
Burgermeister,
That's right. The pond is not stocked yet, but my first order of fish is scheduled to be delivered at the end of October. I'm not in a real rush to get the aerator, nor am I dead set on a solar system. I would like to hear what your thoughts are though. If I can get any useful information on the Malibu Water system I'll post it here. Thanks.
Limb Bream,
I too have a pond that was recently constructed. I'm going to be installing a Keeton solar aeration system in the next month or so. My pond isn't close to an electrical source and I also like the long term savings of going solar.
Your situation really depends on the timing of your house construction. If you plan on building in the next few years, then wait and go with an electrical aeration system. If it's going to be a decade or more, then go solar.
With your pond size, I wouldn't be in too much of a hurry. You can manually remove algae from it pretty quickly with a net.
Whatever you do, don't go the cheap route. Pick a solid, well constructed system and you'll get great production.
Jimmy, I looked at the Solaer SB-1 system. It looks like quality solar panel and high enough current to keep a good sized battery charged. I didnt see anything about the compressor. Can you tell us if it is 24vdc, 12vdc or what. I saw a 24-12 volt converter, but no specifics. You can still buy components and set one up much cheaper, but if the warranty is 5 yrs or so, it may be a good deal. It definitely looks like your pond is remote. No cell phones either, I bet. That's nice.
Here is an email response I received from Luke Keeton. Hope it sheds some light on your questions:
Our Solaer Lake Bed Aeration systems are wonderful! We have been manufacturing them for close to 8 years and are now in their 4th generation. Most of the components are specially designed and manufactured for this specific purpose. Our systems are very reliable and have proven to be almost maintenance free. In the last 5 years we have only had 2 compressor malfunctions and both of these were replaced under warranty. We offer a 1 year warranty on our systems, but we offer an 5 year extended warranty on all of the "wet end" equipment including the diffusers and self-weighted tubing. Also, there are extended manufacture's warranties on the solar panels (20 years) and the charge controller (5 years).
The solar panels are actually very strong. I have seen a manufactures representative punch a solar panel quite hard with no ill effects.
These systems come with a complete installation and maintenance manual and also have technicians available for you M-F 8-5. Our technicians can usually trouble shoot your problems over the phone and get you up and running in no time. The systems are actually very easy to install. All of them are pre-set and tested here before they are sent out, so basically you would just have to mount the solar panels, set the box, drop your diffusers and hook up a few loose wires.
If there is a problem with one of the components it is usually easiest to pull that part and send it in for evaluation. As for the solar panels themselves, we have never had a client with broken panels before so honestly I'm not sure what we would have to do. Replacing a solar panel will probably run you about $650.00.
Burgermeister, I think my decision has been made concerning the Malibu Water sytem. I posted a question on their message board with all the things you asked about and got no response. I called Malibu Water only to find that the lady on the other end of the phone didn't know anything about the system. She did give me her managers phone number, which I called and left a message with your questions. Once again, no response. So if you think that you could help me build a decent quality solar aeration system, I would like to here your thoughts. Thanks in advance.
By the way, it will probably be 2-3 years before I begin to build a house near my pond. So, I'm not dead set on solar aeration if I can wait with no ill effects. I'm not dead set against it either though. Any opinions are appreciated.
Went to the web site for "Solaer". Here's the link:
http://www.keetonaqua.com/products.asp?cat=207 Looks like a good system, but its pricey...least expensive models starting at just over $4000. They say you can recoup their costs in the first year via the electricity savings, but the numbers don't back that up...
Meadowlark,
They are probably factoring in a hefty fee to have an electrician run wires from the box to the pond, which have to be buried. Then add the monthly bill on top of that. If it doesn't pay for itself in the first year, it won't be long after that. That's my guess.
JW,
Yep, you are probably right. I was thinking of my own do-it-yourself installation and it would take about ten years to cross the break-even curve in that case. I ran air lines to the pond, rather than electricity.
I'm building another pond that is completely inaccessible to even air lines...depending on its size, I may try one of these units. Thanks for the info.
JW, I was going to leave your scenario alone, but since it has come back up; any aeration system, if bought, is a do-it-yourself project. At least the Solear system is only component parts, not like a car that you just drive off the lot. The system looks VERY pricey, assuming they said a 120watt solar panel is about $650 to replace. That would be the heart of the system. Lets look at the remainder. 200amp hr. battery, about $200 dollars unless gel cell, then $350. Mounting box, fan, compressor, air line,timer, diffuser,, 400 watt inverter unless the compressor is DC. That's over $3000 excluding the battery and panels. $650 not bad for 120 watt of solar power, 5-6 dollars per watt. The rest seems too pricey and can be bought anywhere. Just dont want to see you get hosed. At 15 feet deep, you need a compressor that will end up being 250-300 watts, so I doubt you can run it more than 8 hrs.daily. Now if you got a second battery and charger for home, and swapped them out every couple weeks, you will be OK for 14-16 hrs daily.
Hope this makes sense. In the LB's case with only 8 ft depth, a much smaller compressor can be used. :Gast has one that will produce 1cfm at 4 psi and uses only 60 watts.
BM,
It doesn't sound too difficult to build one of these, if you have the right knowledge? Any plans?
Have you considered a windmill system instead. They seem to be much cheaper and they are "hands-off" also.
I've considered a windmill, but decided against it due to the fact that there might not be any wind on the days when you really need dissolved oxygen the most. I do like the aesthetics of a windmill though.
I would be interested in any plans for a 3 acre pond.
Or kits?
Frank
burgermeister,
I appreciate your thoughtful input. I'll be interested to see how long the system will run on a daily basis. I'm going to go out on a limb here and suggest that 8-10 hours of aeration is 8-10 times better than no aeration at all. I think I'll get more than that however. Plus, I'm using nature's energy, which beats paying the electric company more than I already do.
As for the cost of the system, you're absolutey right. If I were to do it myself I'd save some money. The same could be said for changing the oil in your car or building a deck, etc.
However, people make a living by performing services for others. Sometimes it's wiser and more cost effective to let someone else do the work for you. In this instance, that's how I feel. I don't have the experience in this matter.
I don't want to rely on a stranger's plans that may or may not be functional. I don't have the time to fix costly mistakes that would surely occur.
Again, I do appreciate your input. I just see it differently.
JW, understood. As, I said before, if a 5 yr. warranty, and they send someone to set it up and repair it; money well spent. From your e-mail from them, and lack of information on wed site, I would be concerned. But, as you said, much better and cheaper than windmill. Don't misunderstand, I'm not in this business and am not trying to sell anything but I DO design and install emergency backup power systems for ship's communications equipment, so this is very simple in comparison. I priced component parts before deciding to run electricity to my pond. Keep us informed of results. Would also like to know compressor type.
Meadowlark, I have solar panels I bought for my sister to run fans with after Katrina, and a small gast compressor, inverter, and such. If this is for your kid's pond under construction, let me know when you need to get cranked up. I will let you test it out. How deep will it be? As you know, that is the big determining factor on the power used. My pond is down to 7 ft. from 11 where the diffuser is. Will see if the gast will push air out(I bought it for $40 from C & H(S?). Send a PM if you need to.
Sorry, LB. I will be testing my compressor in similar size pond and similar depth as yours in a month or less. Will let you know the outcome. I will try to get more info from Malibu on the system you are comtemplating.
BM,
Yes, it is for Kid's pond. Probably only 6 feet or 7 at the most in depth. I say 1/4 acre but that is being generous. I'm game to try out your approach. Let me know. Thanks.
BM, I'm interested to know how it does also. I wouldn't mind making my own system also if it works well.
LB and ML, both your ponds sound just right depth and area for the small system. TKhe thing that concerned my about the Malibu system, is that no battery is mentioned. At a 64 watt panel, that tells me that is is an extremely small compressor and will only run during the day. LB, with you just now stocking, and winter coming on, new pond, yu won't need anything until spring, but will have info by Thanksgiving.
ML, when will yur pond be ready. If you have a pond similar depth, you can do testing on it. What is the compressor you are using on your smallest pond.
BM,
My kid's pond is ready now for stocking...and aeration. It is only about half full, but that will change now very quickly.
The compressor I have (from Vertex systems) is pushing air to diffusers in my 4 acre pond. I don't have one for the kid's pond yet.
I'm open to suggestions and/or experiments...always wanting to learn.
BM,
I'm using your knowledge on this one. I'll be waiting to hear your success story and some additional info on your new product!
Thanks again.
ML and LB, You guys may want to begin some preliminary searching on solar panels. I bought a 45 watt panel at Fry's(which ML can use for testing) for $300.They are more than some, but very high quality, ICP made in Canada, and work on very cloudy days. Harbor Freight has 45watt on line for $200.00, Chinese made. They are supposed to have them in Pasadena, tx., that is, for the Oct. sale. I have a gast 1532 series rotary vane compressor good for 1.25cfm at 5 psi, or 10-12 ft. The solar panel size(watts) depends on how long you want it to run, and how much at night. Remember, panel costs are 5-8 $ per watt. If you want to run the system full time, you would need 150watt solar and 100amp hr. deep cycle battery minimum. No way the Malibu system with 64 watt panel will do that. They dont mention a battery, so assume they are using a very small 12VDC compressor, probably an air brush compressor. This gast is 0.55 amps at 115vac, or 65 watts. There is a DC version too, but probably $200 or 300 unless you can get it surplus. I went to C & H website and they have 2 of what I have for $32.00.(they are new, never used) I paid $40.Meadowlark, all you need is a deep cycle battery and hose and diffuser to get started. You may do well with a piece of soaker hose, or a coiled soaker hose, or stone. I got a diffuser from Aquatic solutions that has a check valve, and operates at 1cfm. LB, you will probably need a check valve to keep water out of system and not have to push water back out at startup. Maybe a soaker hose or stone wont need this. Not familiar with this. Much on aeration methods on past posts. ML, know you know this, it is for Limb bream.
Enough rambling. ML, whenever you want, I can meet you somewhere and give you the panels, compressor, and inverter. You will need a light timer to cut the compressor on and off. It wont run 24/7 with this panel. I'll send your a PM with mobil #.
WOW BM!!!! Thanks for all the info and time you put into this one. I'll start price comparing in the near future.
One more question, AGAIN...
What is the recommended time that aerators should be run during a 24 hour period? I know 24 hours would be ideal; but what time frame is really sufficeint for a 1/3 acre pond 8 feet deep?
I'm glad you asked that, LB. That is what determines the overall expense. To run one 24/7 you would need large battery and high wattage of solar panels. Your and ML's new, small and shallow ponds are ideal for solar aeration without great expense. One thing is that the sun is your friend, in that summer and long days gives more time for charging, and more time for algae bloom to produce O2 in late spring and summer.
I couldn't speel airashun...aration...whatever until I came upon this great forum, so the experts in the field can elaborate and/or correct, but I feel that night aeration with an algae bloom is essential due to it and other plants which may(but hope not)develop taking in oxygen at night. They also give off O2 during the day, but with high temps., above 90, I would aerate for water circulation during the hottest time of day. I'm thinking midnight to 7AM and 2-6PM. That is 11 hrs per day. I aerate 24/7 becaues I have electricity and an old pond with silt and muck. 10-12 hrs. in late spring and summer and less at other times should be good.
There are many past posts on when and how long to aerate and determining factors. I suggest you look at Ted Lea or Cary Martins posts on the subject. Also Bill Cody, Bruce and Cecil, and many others with vast experience. Once you determine your objectives, I can tell you how much wattage and battery size you will need. Also if you will change out battery occasionally or want a self maintaining system.
BM,
Sorry it took so long to get back to you. I'll probably aerate at the approximate times that you mentioned. That would add up to the 10-12 hour range during the spring and summer, and little to no aeration in the fall and winter. From what I've read in other posts, I don't have to worry about winter kill here in south Louisiana. With that said, how much wattage do you recommend for my pond? Also, I was planning on just buying a deep cycle battery (size ?) and changing it out whenever necessary. You mentioned a self maintaining system though.
What exactly is that?
Thanks again!
Jimmy Wheels,
Sorry for not responding to your post from last week. I must have over looked it. If you're still here, thanks for your comments. I appreciate any and all comments I can get.
By self maintaining, I meant that you would not go to your pond for long periods and would want to assure that the aerator keeps running.That's where it can get really expensive. Also, long aeration times, especially during the day while battery is needing to charge.
Some people dont realize just how expensive solar or wind power is as compared to electrical grid. Grid power @ 10 cents per Kilowatt hr. means 100 watts is 1 cent. 100 watts of solar power is $500 dollars or more. That's 50,000 times more. All I'm saying is I am trying to squeeze the most out of a system, by lowest wattage pump to do the work required, which is overcome 8 ft. of water weight to force out bubbles. Deeper ponds, longer run times, etc. push the cost up dramatically.
If you will change out the battery every 2 wks. or so, aerate 6-8 hrs. daily we can come up with a good system, reasonable price.
I will give you and meadowlark a materials list this weekend by PM.
bm
would you please share the details with me? I have 3 acre pond that I would like to use solar. Power co wants thousands to run the grid to my pond site.
Thanks
Frank
Frank, I will be glad to spec. out a system for you. These 2 guys have same small size and depth and need the same components.
How deep is your pond & how old, any vegetation?
How long would you like to aerate?
You may just want to go with a Vertex system sized for your pond; they dont have a system for these very small ponds, but are supposed to be the best. Check them out on the web, let me know which compressor it will use. What voltage and current draw.
burgermeister
Pond is 3 acres. It was built 50+ years ago by grandfather as irrigation pond. Three years ago we renovated, raise the dam a foot, and had trackhoe deepen the edges. Deepest is only 7-8 feet with large parts 3 feet deep. Bottom has lots of muck.
We had severe potomogeton and bushy pondweed but had Greg Grimes treat and is now weed free. We do have some grass carp.
I am not sure how long we wanna areate? Advise?
We generally go once a week and have power at a barn near entrance of property. Power co charged $300 to drop a pole there and wanted thousands to run to the pond. I mention that since we could swap out battery once a week.
Thanks a lot
Frank
Got you, Frank. I'm not sure if bottom aeration would do much good in such a shallow pond, as the lifting effect of the bubbles from depth is what does the circulation. Just how far is the electricity from the pond? any chance of running air line? you can run air thousands of feet without much loss. Surface aeration may be best, but water pumps draw a lot of current.
Why dont you look up Tea Lea, an aeration specialist on the forum and run the pond by him. Let him advise you. Whatever you decide, if you still need solar or electrical advise, I can spec. that for you.
Distance to the pond is about 2 miles so I dont think air line would work.
Thanks
Frank
OK, Frank. Just checking. You may start with a similar setup as ML and LB in 7ft water. If it works out for you' you can place another system elsewhere in the pond if you want. I would sketch out the pond and ask Ted or Cary Martin to help with placement of diffuser.
Hello Burgermister,
It sounds like you know a bit about solar. I have been a long time fan of it but never actually built one. Had all sorts of plans and knew all I needed etc to do a house. My pond is just under a acre, I want to hopefully do some type of aeration on the one side which is about 1/2 acre and six feet deep. Could you let me know how to build a small solar aeretor. I dont want to spend a lot but I do want to do solar/battery system. I read your posts and like you said some aeration is better then none, so a small syatem would be fine to try.
Joey, you can look at the threads(including this one) regarding small, low current compressors. I wouldn't want to steer toward an under aeration situation. PM one of the aeration specialists to size a system. Give them various depths, water clarity, conditions, muck, etc. If you decide to go with solar, I can tell you how long per day(or night) to expect, what size panels, battery, inverter etc that you will need. PM if you like...good luck.
Joey and BM,
Harbor Freight has a 45 watt solar panel kit on sale right now for $199.99 and Northern Tool has 15 watt panels on sale for 79.99. Hope this helps.
I almost stopped at northern tool today on my trip to walmart. I was thinking of the aerator stuff and thought..i got all winter do dont rush. I was just on a sight, looked like nice stuff but big bucks. I have electric pretty close like 75 feet away from the pond so its a option. I was just set on upfront cost then it being free. thanks.
Sorry burgermister I thought you might know where to get the components and stuff like that. The solar part I can build and get, its the aereation stuff I dont have any experiance with, so I dont have the slightest idea about it yet.
Maybe there will be some good adds in the pond mag. I thought would have it by now, come thursday it will be 2 weeks. The girl told me she mailed it out that day....
If you have power so close to the pond I am wondering why you would want to use solar?
I ran my power 650 feet to the pond, and have been running a low amp. pump 1/2 amp draw for a few months now but I have a 1/4to1/3 acre pond for the money I wonder if you could station a couple of the smaller units with 9 inch diffusers in different locations. I am just putting thoughts out there as I havent much expertise with this stuff, only what I have picked up from here. have consider that if my small compressor wasnt working well enough that for 50 bucks I could add another compressor inline and double my air output but it works really well, as far as I know.
Joey, as trialsguy said, definitely consider AC power to the pond; or an airline. You can never get near the bang for the buck with solar. It is just an alternative for very remote sites. The small compressor like myself, trial, and some others work well enough for 1/4 or 1/2 acre ponds up to 10 ft. deep. You said you have 1 acre and want to aerate 1/2 of it that is 6 ft deep. Tell us about the rest of the pond. Is it deeper, shallower, is it shallow with a deeper hole or 2? C & S sales may have more of the surplus units that draw 1/2 amp. Just dont want you to be disappointed. Tell us more.
I recall one of the aeration pros stating they had run airlines as far as 5000 feet to get from an AC powered compressor to a pond.
Why I say I would aerate half is because the existing pond before I made it bigger was a little over 1/2 maybe .6. The way we made the pond bigger was to dig out the new part and then from the outside remove the existing dam or berms. It created a island with a about a 25 foot opening at each end going into the new part. The newer part is more like 8 feet with steeper sides. The old part is where I figure the aerator would be best. I went threw this year with no aerator and I think it went ok but I am sure a aerator will help make things even better.
Trailsguy.. it sound like you have something that might not cost to much to do. Is it something you put together or bought as a kit.
The solar thing was just me wanting to try solar with something.
Here is the layout. I was thinking the aerator could go someplace to the right of the 6ft mark pretty easy. I didnt really want to tear up ground to run lines but it does seem to be the best option. I can put things in the garage pretty easy.
this is the thread on my pump The only think that I would change would be to spend the money on the weighted airline, around a 100 bucks instead of 20 bucks, seemed like a bargin at the time, but I am afraid to get a hook anywhere near it because the line has started to come up a little bit here and there due to me moving the diffuser around in the pond.
I think the pump was 50.00 and the diffuser was 20.00 and 20.00 in the air hose which is 1/2 black poly waterline 100 foot long. I have much more than that in the electrical install and I had to buy 200 foot of wire which at the time cost me 100 bucks the rest I had or my uncle donated to me. I am so glad that I have power down at the pond, I have now wired up the cabin and have power right at the ponds edge to plug in a radio or heck maybe some christmas lights down there as long as I dont draw over 15 amps total I should be ok, I even ran a 10" miter saw down there a couple time but I could tell I had maxed my limit because the saw was sluggish. Only a couple cuts were made.
This is the trench from the house down to the pond
This is my hard worker and this is a picture from the pond looking towards the house
OK, I think I found the pump. It says 1.5 cmf. i copyed the info. let me know if this one is good. One step at a time.

Stock #PC2050 $39.95
yep that looks like the pump and here is the
link for the diffuser that I bought. I dont know if this system is right for your pond but it seems to be working great in my pond. I am sure the exsperts will evaluate your needs and determine if it will work for you. They say too little may be worse than nothing at all. Seems that I have read that in shallower water that you actually need more diffusers due to the lift capacity or the volume of water being cycled up. deeper water allows for more circulation hydralically if I remember right? The pros will let you know, they are a great bunch of people!
Great pictures trialsguy! The picture of your helper is too small, though. Can you put in a larger one?
Hi Joey -
I am worried you may be underaerating your pond if you only use a single disc. The compressor you are purchasing could run 2 single discs, but even then I don't know if that would be adequate. The best thing would be for you to post or send me a map to scale so that I could determine the volume. Then we can determine how many discs/diffusers you need to circulate the volume of your pond atleast one time per day. I think you should consider having a diffuser location in the new section of your pond as well since it is deeper and it is on the other side of an island where it won't benefit from the aeration.
I am glad you are considering electric rather than solar. When you need aeration the most is at night and when you have a few cloudy days.
Hi Sue thanks for taking a look. Here is a layout. I didnt have a scale so I drew it and labled it, measuring it from my survay. The spillway is in the far upper right hand corner in the new part. The pond is spring fed. I have been told seven springs but its not confirmed. I do know I have about 4 to 7 gpm out the spillway pip depending on season. Summer I had days of 0 and days of a trickle now its picked up again. Just a quick note, I didnt have any aeration this year and things went OK. I worried about it but it all worked out. I have a few types of fish. Hybrid stripers, Large mouth, Channel cats, 3 types of sun fish, and a few things I want to get rid of. I did not fertilize this year but did start a feeding program. I was thinking I would like to do things gradual, like fertilizer but just easy not to much and the aeration from what everyone says is a good improvement. What can I expect by aeration? More fish? Better water? etc. Thanks I am new to ponding but I am hooked. Excuse the drawing I did it with a mouse...
Hmm I dont recall downsizing that picture? Thats one of my favorites.There we go I inlarged the photo for you Sue.
These are the numbers I came up with based on your map (I measured it out on graph paper according to your dimensions)
The CFM is based on the compressor you are considering and our coActive AirStation is basically like 2 of the separate discs sold by Aquatic Eco. My calculations show that that compressor and 2 discs would not be adequate. I recomend atleast one 'turn over' per day and with this set up you would be under that at .88.
I recomend you go with a compressor that puts out atleast 2 cfm and something comparable to two dual diffuser disc AirStations.

"What can I expect by aeration? More fish? Better water? etc."
An effective aeration system brings oxygen into the water, eliminates stratification and increases circulation. This makes the water at all levels able to support animal and plant life, control algae growth by limiting its food source, and aid decomposition of suspended organic material and muck on the bottom of the lake.
Joey - where are you in NC? If you are close to the mountains at a higher altitude your cfm and psi will need to be adjusted.
Joey and Sue,see hows this fit, Vertex Air 1 Mini with additional (2nd) diffuser (Air2 Mini), 2.5 cfm total which would allow for a minimum of 1 cfm per station and the ability to turn more and (different) gallons than any single diffuser.The lift on one Flex Air would be approx 1/4 that of two discs working side by side or "CoActive" thus taking advantage of the "synergism"Sorry about getting brand specific but is the only 2.5 cfm piston pump that I know of,Rotary vanes do well when starting with 4.2 cfm open flow,which may be a lot of cfm for your situation Ted

Measuring according to the map you would need approximately 300 feet of weighted tubing and 150 feet of the non weighted.
Wow 1.26, some how I calculated about 3/4 of a acre. I thought I was closer to 1 but I found a pond size calculater and figured it around 3/4 with approx 1 mil gallons. I better do my homework... I know you guys have great systems and I would love to get one that really kicks butt, but I cant spend 1000 bucks or more by the time I am done with this. I was hoping a few hunderd and I would have something at least good.
Sue I am between Hickory and Charollet, not really mountains here.
Thank you Ted, I will browse around on your and Sue's web sight to see what you all have there to.
Joey, I figure .657 acres with an average depth of 4-5 ft would put you in the million gallon range, you can get a central diffuser to turn that many gallons one time easy enough but you will find a lot of the gallons being turned much more and many in the shallows considerbly less than that, This is where sizing comes in, and thus the reasoning to stretch out the diffusers, A deeper pond with the same gallons (less surface acraege) would turn more with fewer diffusers because there will be more gallons lifted by the vertical current as it entrains more gallons on the way to the surface. The deeper the more effecient but you have to work with the depths you have.
Hey Ted, where have you been and how are you?
Joey, I agree with Ted about the 0.657 acres putting you in the million gallon range. I am located in Burnsville, just west of Marion. If you need any on-site help, please do not hesitate to contact us, we would be more than happy to run out to your site.
Hi DD1 been OK and thanks for asking. Have been very busy this season which starts in March and goes hectic until about now.Hope to have some more time for "The Boss " for next several months. Also hope to see you and and all our pond friends in Austin, thanks again Ted
