Look closely at this photo provided by our friend RAD. This is an example of a shrimp farm in Thailand producing ridiculous densities of shrimp with electric driven pond circulation. I don't believe that my density will be anywhere close to what these guys are producing. Keep in mind that I'm not in any way implying that I think this is better than standard aeration. I just think that it may possibly, in some situations, be an alternative method of keeping pond water quality up to standards. Definitely not for everybody, but maybe something to give someone else something to think about.

No, I believe that's a plant.

I just made that comment to see if it would make lurkers look back at the pic to see Rad.

It's a generally accepted fact that if you don't drink Diet Dew that it hampers your ability to evaluate digital images.

Rad : How does that setup work ? I can't tell from the pic. because I don't drink D. Dew and therefore I don't see in 1s and 0s (digital).

Don't make me start posting in binary!!
You don't want that.
EDIT: Don't make me get binary on your ass!

ewest, Bruce has another picture, a close up of the paddles, they look a little like kitchen spatulas, the ones with the holes in them. They aerate and circulate the water at the same time. Our power is 250v 50 cycles and is reasonably inexpensive. It's pretty scary, there is a lot of bare wire, motors in standing water and wire used in place of drive belts.

That sounds a lot like the systems used by the catfish farmers in the Miss. delta. There source of power is tractors and they use paddle wheel systems.

Man, you guys aren't going to believe this without a picture, but I hooked up my circulator last night and let 'er run for an hour, and I turned my 1/7 acre pond into a river! I had cattail stalks going by me at about 1 ft. per second. Another cool thing is that it didn't affect the yellow perch or the bluegill in the slightest. They continued to eat pellets and were biting on jigs within two minutes of turning the rig on. I've asked this before, so I'm sorry for the repeat, but what is the formula for energy costs of a 3/4 hp circulator 110/120 with 6.7 running amps? I'm debating whether to run it 24/7 or to run it during the night to oxygenate and keep the pond from heating too much in the hot summer sun. Between running the sweeper nozzles one way down one bank, and the circulator the other way down the other bank, you may not be able to get a light lure to get to the bottom! I'll be carefully documenting O2 levels throughout the summer, but I think this device could work quite well on a pond that is considerably bigger than this one. Also very cool--the feeder went off during my test, and the pellets spun around the pond, about ten minutes per lap and the yellow perch chased them down. The pellets stayed in the current and never went to the shoreline, which may have the added benefit on breezy days of not pushing the pellets to the shore as often happens with a vertical diffusion system. As many of you already know, those pellets end up rotting, or feeding turtles and froggies. I'll also be documenting shoreline erosion issues. I may have to set some flat stones along the first bank that the current hits from the circulator.

Yep, FrankieBruce has been in the Dew cabinet again.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Bruce: 6.7 amps running 24/7 is 6.7X24x30 = 4824 amp-hours per month. Multiply by 115v to get volt-amp-hours (watt-hours) is 4824x115 = 554,760 watt-hours per month, divide by 1000 gives 555 kilowatt-hours per month.Check your electric bill and you should be able to see how much a kilowatt-hour costs you, delivered. IIRC (and it's a WAG) a very ROM figure nationally is $0.11 per kilowatt-hour, which would be $61.05 per month, IF my math is good and IF that $0.11 per kilowatt-hour is valid. Your own electric bill is the best source on cost anyway. P.S. Are you still claiming that empty DMD can is in the photo just to provide info on the size of the hardware?

That thar's some good info. The can's not empty. I keep full ones sitting around for emergencies. Don't even care if they're cold!

I have learned something. A .75 hp horizontal aerator is awfully big for a .15 acre pond! After installing and turning on the unit the water stayed at saturation for oxygen continuously, but the clarity started to deteriorate. Secchi readings dropped from 26 inches down to 8 inches and the water turned brownish from suspended sediment. I've sinced turned it off and the secchi readings are creeping up about .5 inch per day. I am going to move the unit to my 1.25 acre pond and try to switch to a surface agitator in the little pond to work in tandem with my two horizontally oriented sweeper nozzles. My DO is still virtually 100 percent saturation, but I've seen that change quickly in the summer so I'm not taking any chances.

OK, remember how I had a horizontal aerator running? I had two sweeper nozzles running one way on the south edge of the pond and the Kasco aerator running the other way on the north edge. Well this created too much current. You could almost get dizzy watching the surface of the pond. The unfortunate side effect was that suspended sediments were keeping the water an unsightly brown and inhibiting plant growth. After turning off the aerator I moved it to my big pond and it is currently transecting the pond with a nice current and the clarity is remaining excellent at Secchi readings of 25 inches.
Now I've purchased a 3/4 horsepower surface agitator. After installing the unit I was completely shocked to see how much agitation comes from a unit this size. I thought it was a malfunction at first! The crown of foam was about three feet high and at least 6-7 feet across. Supposedly we're going to see a delivery of O2 at 2.2 pounds per hour. The sweeper nozzles are still providing circulation, but maybe only 1/4 what it was. Secchi readings have jumped back up to about 12 inches and are still improving. I plan on running continuously, but have considered the possibility of running only at night to keep from adding too much heat into the water column. It will be a fight between the cooling of 16 gpm well water (later to be increased to 24) and the heating of the surface agitator. I hope the YP bear with me as I work out this system.
My Dad can regularly catch perch from 7.5 to 9 inches right now with a rare bluegill added in.
I'll keep you all informed of developments.

Bruce be careful with our YP as we all have a lot invested in them. :p We let you get by with boiling a few alive in the hot tub , and warned you about trying to tan them with reflective foil from the window and even let slide the tidal wave surf set up. But I don't know about shaking them to death with a super sized tsunami agitator. Please don't try anything unusual with those mean RES they will surely decapitate you.

I second that. They are all gonna get an O2 high! My wife bought a pump for her beta aquarium, and the little guy cant even chase his food down. I'm gonna have to pinch off the supply tube.

Theo: I have four squirrels that have given up water skiiing for surfing in my pond.
ewest: If the RES decapitated me it would at least be a merciful end.
burgermeister: That's funny. I already think that my fish are in a constant state of sedation from the salinity. They fight really hard, but they're awfully lazy when it comes to biting. The O2 high will probably make them wobble when they swim.

Some news that's exciting for me anyway...
My horizontal aeration pond is clearly cooler than my regular ponds.
The surface temperature two afternoons ago was 71.5 F. and the other ponds were at 74.5 degrees. While this may not seem significant, it could be the difference between life and death for some cooler water fish.
Anybody in Texas who wants to have some smallies, or in Nebraska who wants yellow perch, or in Michigan and wants rainbow trout might be able to benefit from this.
I am currently running the surface agitator during the night to add oxygen, but not heat to the pond. The sweeper nozzles are running 24/7, but still only 16 gpm between two nozzles. Very encouraging.
Not water skiing squirrels were noted.
