I have a 75 FOWLR with a small grouper and a damsel in it. Recently, my live sand(a fine sand) has started to have a dark brown buildup on top of it that kind of mats the sand together. Is there anything I could put in the aquarium to keep the sand clean and white. I've heard that huma triggers swallow sand and spit it out through their gills. Would this work? If not, is there anything I can do?
