Great pond aerator
Size: ≤ 5,000 Gallon
Excellent pump for our pond as a secondary aeration pump. Really easy to set up and it's almost silent. Nicely made, this is a quality pump and air stone that will help keep your pond aeration at a healthy level for your fish. Definitely worth the investment!

Almost perfect. Needs additional hose clamps.
Size: ≤ 5,000 Gallon
Works well. Only downside to the kit is they don't include but just one hose clamp. I had to buy 3 more. The included hose clamp is to secure the hose to the included airstone, however the vibration of the pump causes the rubber adapter to slip off the pump outlet. I also added a hose clamp to both sides of the valve to asure they stay attached. I bought a second kit after about 2 weeks during Prime days to add to my setup converting a swimming pool to a wildlife pond. So it works. Highly recommend. Just buy a box of small hose clamps while you are ordering.

Not Disappointed!
Size: ≤ 5,000 Gallon
Bought for backyard pond and glad I did. I have a joining in my backyard and I’m all honesty, it had to many fish. Purchased this because my brother had recently purchased a similar device and was impressed. Worked great all summer and the aerator has prevented the pond from freezing completely all winter long. Live in Rhode Island and this winter has been colder than the last several years. So we have had more days with high temperatures at or below 32 degrees. Even with multiple snow storms and prolonged stretches of. Old weather , my pond hasn’t frozen over completely once. (I also reduced the power for the winter because it is in the shallowest part of the pond.)
