Hello I was wondering if it matters what ppi of sponge filter I use. I was thinking 20ppi would be good because it wont get clogged as fast and probably has a better flow for biological filtration. Is there any reason I should rather go with 30ppi thank you for your time.
EDIT: I guess possibly a finer ppi might be better with really really tiny larvae?
