Aeration Pumps Male Airline Adapter (1/2" NPT x 3/8" Barb)
Very strong pump
Bought with the quad air diffuser for my koi pond. Runs 24/7 and puts out tons of air. A great investment for your fish.

This is the second one I have purchased. The first one ran for years before it needed repairs. Parts were available. Ran for several years after repair before I decided to replace it. Got larger one this time, I like equipment the stays the same model after model and parts are available.

A fine product
I had read that some of these pumps are noisy or that they do not pump well enough. Well in my experience, the 40 sized pump works very well and is feeding two sandstones which are bubbling to a large degree. The pump is positioned outside under an artificial rock and when I walk up to the rock it is no more noisy than previous smaller pumps that I have had so that is not a problem noise or volume of air produced.
The only thing that was a problem is that it is not easy to find adapters to get from the large output to those of the 1/4" hose and sand stones plus making a T with the water hose adapters was how my T was accomplished. This needs to be worked on but is NOT the pumps fault.

I HAVE BEEN DOING PONDS/FISH FOR MANY YEARS. I HAVE THE 40 AND IT WORKS GREAT. VERY QUITE,PUMPS LOTS OF AIR. I HAVE 7 AIRSTONES AND THE ARE ALL BUBBLING LIKE CRAZY.
I HAVE HAD MANY AIR PUMPS,THIS ONE, SO FAR, IS AS GOOD AS THE MORE EXPENSIVE MODELS. MY AIRSTONES ARE BETWEEN
18" AND 36" DEEP.
