I'm using bio balls in my canister filters (currently in a fishless cycle) - I know they work better not submerged but I bought them before I realized that, so I'm going for it. Besides, I just added some Matrix on a different level, so that should help. Anyway...
How long can my bio ball trays be out of the canister in the air while doing a canister cleaning? Or Matrix for that matter. I can't see any little biological critters gasping for oxygen, but I'm sure they're there.
