Fine Pore Diffusers by Sweetwater Universities & Schools This surface skimmer will doSweetwater fine pore diffusers are the same high quality as our regular Sweetwater diffusers. The difference is in the smaller pore size, which produces finer bubbles.

The bubble uniformity is excellent. All fittings are PE (polyethylene) unless otherwise
