Pond Boss Forums AERATION Systems questions Opinions on this set-up please

Hello all. I would like to aerate this year, and keep it nice and simple. I have a 1/3-1/2 acre pond that was done in 2011. It is stocked with blue gill and LMB. We are in Buffalo NY and this has been a terrible winter. I am so worried to see what happens when the ice melts from the pond. The pond is 18-20ft deep in the deep end and then dog-legs around to the shallow end getting down to 5-6ft. The closest electric is about 200 ft away. I would like to put the pump next to the electric and run one air hose down to the pond, then convert to weighted line and put a single diffuser in the middle of the pond in the 12-15ft range. I want to do something but I dont have the funds to go crazy, im trying to keep this at $500 and under. I realize the best thing to do is probably run two and put one in the deep end and one in the shallow end. If I have to, I will, but it will obviously add a bunch to the cost. So does anyone have a one diffuser system that woks in a pond that looks like mine? What do you think? I have attached a bookmark to three pond pics, hopefully the link works. If it does and you see the pictures, the first two show what it looked like being built. The 3rd is when its almost full. The pond is filled with natural runoff from a 30 acre field above. Thanks!!

I sent you a P.M.

Here's the deal. To do it properly, and to prevent winterkill, you need two things.

1) You need to calculate the gallons of water in the pond.
2) You need calculate the numbers of diffusers needed and volume of air needed to bring at least 125% of that water volume to the surface every 24 hrs. 200% is much better. If the pond is 20' deep, you need that volume of air when the compressor has 11 psi of backpressure. (10% for a fudge factor)

You should be able to find the specs on the diffusers in regards to operating pressure/volume and amount of water that it will move at "X" depth. You have to check the pressure/volume curve charts on the compressor to make sure it will generate the amount of air you need at 11 psi pressure.

If one diffuser will do that, then you can get away with one. You need to move it to 4'-5' below the pond water surface for the winter (diffuser set at 4'-5' depth), then move it to the deepest spot in the pond for the summer. You cannot leave it in the deepest spot for the winter. If one diffuser can't do that, then you can't get away with just one diffuser.

esshup, thanks for the info. Man its a lot more complicated then I thought!! I apologize for the lack of pictures. It used to be so easy, then google took over everything and I hate it. I am tr ying to figure out how to do it with my pictures on picasa all over again..

This these ideas of how to post pictures. Newer info is more toward the bottom of the thread.
