The aerator replaced a much more expensive model, which had failed after about three years. I was concerned after receiving this product that it would not do well in our three-quarter acre pond. The site is deceiving and sent me a generic number versus one that could possibly do a large pond. After Plumbing, the unit which was very simple it basically drops right in And has very nice vibration dampeners attached. The negatives are the fittings were smaller than original and basically one off for this unit, and it is not designed with an optional split for two hoses like we have used for the diffusers. So far the quality has lasted as we use the timer Which I found easy to set up. It’s been running for a few months, so we’ll see how long it actually lasts. As long as it last a few years, I will buy another.

Everything works as des y/as it should expect for the WEIGHTED air hose. It is floating just submerged or at surface of water. Is not sinking as a weighted air hose should…

works great ran power down to enclosure box plugged it in, working good helps clear water up but does not seem to get rid of algea or duck weed. I am buying White Amers and Coy fish to help take care of it. It really does clear the water up clearest I have seen it in 20 years. These are the best ones I can put on the other even clearer ones must be to big will not download. some of those bottoms you see are 6′ to 8 ‘ deep”
