I moved into my house about 4 years ago and when I got here there was a small fountain in my pond and I want to go a step above that this spring and aerate my pond.

I am disabled vet and would like to do this as cheap as possible as I am on a fixed budget. I would like to make my own system with a compressor that I can rebuild myself.

Read through this Aeration Thread from our Achives section. Near the bottom I put numerous links with good information about numerous topics about homemade or do-it- yourself aeration. Do lots of homework before pulling the trigger. A poorly built system with too little mixing is IMO a waste of money both in parts and with a system that wastes too much electricity and does not result in efficient mixing of the pond. Inadequate aeration is discussed in a couple of the above links. IMO it better to have too much aeration than too little. With overkill aeration you can do less than 24/7 operation each day. Reduced pump run time lengthens the life span of the compressor the most expensive part of the system.

The basic rule for aeration is the more bubbles you make and the smaller those bubbles are the more water you move. This information came from Aquatic EcoSystem (Pentair) hints in their catalog.
Too small of bubbles tend to clog more quickly that causes extra maintenance.

From your picture it looks like you may need to have 2 separate diffusers to get good top to bottom circulation throughout the pond.

should I use a gast pump. I am looking for something energy efficient and rebuild-able.

what is better for longevity and the above perimeters, a rocking piston or a rotary vane. noise is not a problem, but I dont want anything too loud.

Take the surface area of the pond in acres, multiply that by half the max pond depth. Multiply that number by 325,851. The number you come up with is the number of gallons of water you need to move at a minimum every 24 hr period, I would recommend moving 1.5 to 2.0 times that amount of water.

Since this is a DIY system, I can furnish you with the formulas and information for you to figure out how much CFM you need.

Here is a chart showing what the Vertex diffuser disks move GPH wise, and they need a minimum of 1.0 CFM per disk to work. At 14' max depth, your system will need to generate the volume of air needed at 9-10 psi. That gives you a few psi for fudge factor.



Rotary Vane, rocking piston or diaphragm compressor, they all are rebuildable; but you need to contact the place where you buy the compressor to see if they have rebuild kits. Vertex has rebuild kits for all their compressors.

Here is what I did for my DIY aeration. First off I read most everything on here concerning what to do and not to do. These guys know their stuff.
I went to www.hoosierpondpros.com that is linked above in Esshap above note and purchased my weighted tube and the Vertex diffusers. I only purchased the disks and built my own bases like many on here had done. I am about 17 feet deep so I went with an ebay rocking piston compressor. Between parts from Amazon and Lowes I pieced a manifold together and got mine all running. I am going to add 2 more diffusers to the shallow end that will mainly be for winter de-icing.
good luck and there is lots of info on here.
Dave

I will take some time this evening to do the math, but before I can do that I need to know the surface area of the pond, and the maximum and average depth. Then I can run the calculations and tell you how much water you will have to move in a 24 hr period. Without knowing that information, there is no way to know what sized system you need.

It's up to you to call the different companies that supply compressors, fans, and other equipment. You will have to find out from them how much Gallons of water their diffusers move, and how much air their compressors supply at what pressure. After all, you wanted a DIY system, not a do it for me system.

Once I have the size of your pond, etc., I can PM you with a quote on the individual parts. i.e., compressor, cooling fan, diffuser assemblies and tubing from Vertex.

I am starting to get algae really bad and I dont want to treat with herbicide. I need to order a system by thursday!!!!!!!!!!


thanks for all the help so far


the pond is 14 feet deep at the deepest and gradually goes up to shore that is all I know

please give me a ruff estimate of what I need

We need to know where surface area. How large is this I cant see your attachment anymore. Unfortunately adding the aeration may not help. In fact I doubt it will much. Mine is running and I'm getting FA I may need to treat mine but I'm waiting to see if the upcoming rain will help. Good luck.

Title of this thread says 1/2 acre.......

If I did the math right....Assuming 7 foot average depth, the pond holds about 1,141,000 gallons. So to turn the pond 2 times running a diffuser 24/7, the diffuser needs to move about 1600 gallons/min. Based on that and the chart posted by Esshup, 1 XL1 Vertex diffuser placed at 14 feet should easily do the job.

Depending on the shape of the pond, you might want to go with two diffuser stations placed to maximize access to all areas of the pond. You could then cut down run time on the compressor and save a few bucks on electricity.

thanks for all the help guys

what system do you recommend I get

there are some on amazon that I have been looking at like this

Installing 4-6 aeration systems in your pond will not rid the pond of the algae. Algae is due to a nutrient problem and aeration does little to change the nutrient balance in the pond.

I could not find how big the pond is??
That system linked to on Amazon is only a single head rocking piston pump that does not produce enough air volume for a pond bigger than 0.2 ac. I think two diffusers are almost 1 too many for a single head rocking piston pump. Each diffuser does not receive enough air volume to operate efficiently.

IF you are spending the money pay the extra $$ for a dual head pump that produces twice the air volume. It will opreate 2-3 diffusers well for the larger pond(0.3ac+) application. the dual head will mix the pond faster and the pump will not need to operate 24/7 and thus it will last longer - probably double the life span. Use a window air conditioner timer - 3 prong plug. In IL run 2-3 diffusers. Run time will depend on size of the pond and how old & eutrophic the pond is.
