Having found 6 fish and 3 shrimp in one of my canister filters, I'm planning to put sponge pre-filters on the intakes. (My pipework is DIY Acrylic.) I've always avoided these as I felt they must hold the filtrate in the tank, and reduce the amount that makes it through to the canister.
Any thoughts?
I've also wondered about getting CRS (or similar). How to sponge pre-filters rate against the stainless mesh filters you see sold for shrimp?
