Pond Boss Forums AERATION Systems questions Best pump to aerate 1/2 acre 13'

Bob V and BigBamboo,

I've been using 9" disc diffusers from Diffuser Express for two years now. No problems to date.
If you are interested they do make diffusers with 0.5 mm slits as opposed to the 1 mm slits. When I ordered, I had to ask for the 0.5 mm diffusers. They may be standard now.
