Ive had my fuge going for about a month now. Everything is going well my algae has tripled in size. Ive recently noticed an army of critters living in the fuge. I have a bunch of filter floss in the baffle leading to the return pump can these critters get through this floss? I definetly want my fish and coral to get a crack at these guys. Also it looks like the algae is sending runners to burrow into the sand is this normal?
