Ok I want and looked it up myself. CERITH SNAILS eat brown alge crabs basicly don't help the situation. You have to get sand sifting snails.
P.S. I was asking for a more detailed answer than "A CLEANING CREW" but thanks anyway.
I just siphon them out during a water change. They'll go away eventually....In my new tank, I'm not even bothering with it like I used to with my previous tanks. I'm letting it go through it's own stage and it's starting to go away.... :happyfish
