After many years of fresh water fish, I decided to try salt. I have a 90 gallon with coner flow with a 20 gallon sump. I decided that since I want to go with corals I would try the deep sand bed theory. After much searching, I purchaced the Aragamax suger sized sand. I had read thories for both washing and not washing the sand before use and the LFS said they never wash the sand because there are benefits from the smaller particles that get rinsed away. To make a long story shorter, I added the water, adjusted the salinity/specific gravity, got it on temp and circulated for a few days. The I added the sand. Placed the bags in the tank and cut them open. The water was very cloudy and I couldn't see 2 inches into the tank. Everyone says be patient, it will settle. It has been 3 days with both a HOT Magnum w/ micron filter and a Fluval 404 with carbon. There does not appear to be any clearing in sight. Any suggestions, or should a wait it out? Today I shut off the overflow to reduce the mixing of the tank and I'm just running the two filters. Any help would be appreciated.
