I installed a pump in my pond to circulate the water.It's on a float about 3ft under and is plumbed to shoot water about 5 ft in the air.I've had two pumps go bad in two months.I've been using sump pumps from menards.They take them back under warranty,but it is a pain changing them all the time.Does anyone know of a good pump that will run all the time.I'm thinking of using one of those septic areation pumps mounted on the bank and running a plastic line to the center of the pond.At least i could work on it without using a boat.

Here in the North-East, some put a pipe on the bottom of a pond. small holes drilled every few feet. Then they pump air to it. It mixes the water pretty good.
Don't have a link, but I'd suggest a submersible pump for a water garden; they're designed for continuous use. I get 5 years or more out of a 4200 gph pump; the last one was about $125.00 as I recall. If there's a lot of trash, you will have to periodically clean the intake.

I manage a stocked lake for our local sportsmens club. We put in a commercial surface aerator mostly because some members wanted to see the water squirting in the air - was a mainetmance headache, finally we threw it out after spending 100s on it. The air in the lake bottom is the only way to go if you really need aeration. We have never lost any fish so my recomendation was that if we did its cheaper to just buy some more fish.

Gast mfg. vane pump. $200-300 depending on horsepower.Depending on size of pond you'll need a few aeration stones. Stones are about $15 each.We have 5 in a 3/4 acre pond that is 15' deep. If your pond is over 12 feet deep float the stones at about 10-12 feet. Any deeper puts stress on the pump. Always good to float the stones a foot or two off the bottom. Keeps them out of the mud. Pond is most efficient if 220 volt but can be rewired to 110 volt. No need to run in October - November if your pond "turns over" because of seasonal cooling. You should run during winter but would need signage if the pond would normally freeze because it will have open water.
The hose is special at about $1.00 a foot.
We took a blue plastic 55 gallon barrel cut it horizontally hinged it and used it as an enclosure for the pump on the shore. Drill 4" holes for ventilation on the sides towards the top. You can get the blue barrels from schools where they get juice for lunch.
All this is available from pond specialists in your area or from the DNR in your state.

I guess I could supply a little more detail.
The pump will have a 4 or 5 outlet manifold with adjustable valves. You locate the stones around your pond in deeper water. To sink the aeration stone and hose tie a brick or 2 onto it with 18-24" nylon cord and fsuspend it off the bottom with an empty plastic half gallon bottle (bleach or laundry detergent bottle). Use enough nyon cord from the stone to the bottle so the bottle will be 3 feet under the surface. Should you later need to retrieve the stone you will be able to snag the bottle with a garden rake.

We use a 3/4hp 240V Gast rotary vane compressor with diffusers to take care of our freshwater prawn ponds and also have a 1/3 hp 120V Gast regenerative compressor for a backup unit (has never been needed in 4 years). My most distant pond diffusers are in a pond located well over 400ft away from the compressor. We will be having our 4th annual prawn (shrimp) harvest next weekend, Sept 26th.
"There is a better way". Buddy of mine from college manufactures a pond aerating system that doesn't use big HP to shoot water into the air, or air into the water- uses small HP to pump the water DOWN, setting up water circulation in the pond, and pond is aerated from the air-water interface. Works so well that they have gotten trout to spawn in farm ponds (ask a fisheries guy how hard that is.)

Hi Ray,
Install a suction intake strainer. Take a piece of chicken wire rolled too a 3"dia x 36" long or so, then pull a pair of nylon panty hose over that, then fix too your pump suction.
Install a surface discharge pipe. Take a piece of plastic hose thru a tennis/styrofoam ball(float), seal/glue with silicon to the tube. This removes any discharge static pressure from the pump.
