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?
Agreed Bill. The intent of surge cycling,repeated expansion and contraction of the membrane, is to clean the pores/slits out, and not for removing surface stuff like algae. You need extra hardware to do this plus some technical skills.
Common practice in some Aquaculture venues. My MBBR's will be surge cycled based on a number of variables of the system.
Fun stuff tho!
