Fine Pore Diffusers by Sweetwater Universities & Schools polypropylene filter cartridges and otherSweetwater 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. Sweetwater fine pore diffusers do require higher pressure (about 5 H2O more) and more frequent cleaning than our regular pore diffusers, so they are not typically recommended for regular aeration. The bubble uniformity is excellent. All fittings are PE (polyethylene) unless otherwise
