Airmax Eco-Systems 001040 Pondair Four Stone Pond Aerator

Item came nicely packaged with easy instructions. This was easy to install in my outdoor fish pond. However, the air lines wanted to float so I had to weigh them down with light rocks and zip tied hose’s together where they shared a pathway to consolidate hoses near each other. One of my check valves was not working by not allowing air to pass through it and through the air stone, so I messaged the seller. I waited several days with no reply and then called Amazon customer service. They could not send me just the air check valve and instead sent me the entire unit again for a replacement. I took out what I needed and returned the package. Seemed like overkill, but end result is that now all 4 air lines are producing air bubbles as designed. I’d recommend this unit. Works well. I didn’t rate the longevity because I’ve only had it working for a week or so now. I hope this will last a few years at least. Some reviews complained about noise, but I find it to be fairly quiet. You have to expect some noise level but I don’t pay any attention to it.

Works great but one of the output lines doe not function

Easy to install, great bubblers, our fish love em!

It is so quiet and easy to install

Since installing it has keep the Algae growth to a minimum in garden pond!
