  • Works very well
Size: 2.8 CFM Ponds to 8,000 Gallons Color: Air Pump Only
I needed to replace the bubbler in my 5000 gallon pond quickly. The one I had had for years finally died and we were getting ready to go out of town for a few days. It arrived quickly, was easy foe me to install and works very well. The price was right too - I spent twice as much on a Danner air pump and it only lasted a few years. Thank you so much for your quick service and easy to install air pump ... show more

  • Great air pump, but I dont feel it is a 8000 gallon air pump
Size: 2.8 CFM Ponds to 8,000 Gallons Color: Air Pump Only
First of all, they sent correct pump in my second time purchase. They previously sent a Ox-generation pump 7000 to me. That pump is more expensive than this one, but only 5000 gallon. It is great, but somehow I expected more for a 8000 gallon. I tried to hook up 3 ways: 2 goes main pond 5ft deep, 1 for a goldfish pond 2ft. The main seems lacking of air pump, with just one pump air. Goldfish pond does not have air go into. I gave up the 3-ways idea and just focus on main pond ... show more

  • Fantastic product
Size: 2.1 CFM Ponds to 5,000 Gallons Color: Aeration System
Purchased to use during our warmer weather fishing tournaments to put oxygen into our holding tanks. These are perfect for this use.

  • Great product!
Size: 2.1 CFM Ponds to 5,000 Gallons Color: Aeration System
Works great! Clamps could be a little more durable. One of my discs was defective and they sent me two news ones right away!

  • On the fence
Size: 2.1 CFM Ponds to 5,000 Gallons Color: Aeration System
It is a good aeration product however it comes with two round air stones. One of which cracked in half on me the first week I owned it, rendering it useless

  • So Quiet
Size: 2.8 CFM Ponds to 8,000 Gallons Color: Air Pump Only
I was not expecting this type of quality. My Pond is roughly 14 feet deep at the deep end. I made my own diffuser with a piece of tubing, and drilled a bunch of tiny holes in it. I also ordered a standard air compressor hose which does not need weight. My pond is roughly 1 acre. It stays on 24 hours a day from May thru November. It is almost silent. Moves alot of air through the water. It's been a couple years now. Stays outside even in the rain. ... show more
