I currently have a 180 tank 24" high and wide. Housing a large assortment of soft corals, mushrooms, and zoos. Lighting is 800 watts of Mh and 200 watts of Pc. G-3 skimmer, with homemade sump. Water tests are all in the zero range PH id 8.3, salinity is 35-36. Anyway, I really would like to get a clam but, I would like to know if I can.
