re: Submersible Pump Recommendation For Pond

I have a pond about 1/2 an acre and used a septic pump, weighted hose and diffuser. Saved a lot of money because the regular aerator pumps were very expensive, didn't have a long life and were very loud.

A good aerator is around $150-200. The weighted hose was $1 per LF and the diffuser was around $20. These prices were last year when I bought them. You can only hear the pump if you're standing right next to it. Only downside to a septic pump is you can't put the diffuser more than 10-12 feet deep because of the pressure. Luckily power wasn't an issue because my pond is only about 150ft from the nearest outlet on my house. Another benefit about the septic pump is they're built to last for years and when it does go all you do is buy a diaphragm rebuild kit for about $20-30. And the weighted hose buried itself within a couple of months so that was nice.

There are videos on youtube on how people set them up using septic pumps if you look.
