Surge cycling a membrane diffuser has a lot of variables. Two main ones are 1. type or composition of the membrane, and 2. what is growing on the membrane. A third one probably is the size of the pores. I get algae on mine that I have to scrape off with a razor blade. What about bacterial, algal deposits / mineral accumulations in the pores - slits?
