I set up a 90 gal. reef tank and I thought I was doing so well.I put in 50 hermit crabs ,some snails ,then started with afew fish[clowns and then a couple of cardnials],a couple of corals.This has allbeen done over a course of 6 weeks or so.Now I seem to have developed a algae of some sort.It is slimey green and has bubbles attached to it.I am in the process of checking and lowering the phosphate levels the phosphate.What else should I be looking for and /or doing?
