Dog walker, fish feeder, whatever my wife tells me to do

Product is cast metal, quality power coated finish, clearly made for outdoor use and well engineered. This is a commercial quality product that delivers a very good volume of air and is more quiet than the previous pump that produced less air volume. I am using the pump year round here in Ohio without issue for a 3,500 gallon koi pond.

Pond aeration

Unit is too small for my pond, I was aware of this when I purchased it, but seems to be working fine. I will add on and upgrade as I can afford it.

air pump

Am using on septic system to replace a "Jet aerator" and am glad I switched to the Hakko Air Pump. Pumps more air than needed so have to vent the excess. Will have to wait and see long term how things work out.

Ponds Owner

It's a great little aerator. I have 2 of them, one in each of my ponds and I run them 24/7. They keep the water fresher and their residents healthier & happier & more active. They're great little machines that keep going & going & going & going.
