I am in the process of setting up a 60 gallon cube saltwater tank and my local fish store told me to put in about 4" of sand, which I did. I purchased Carib-Sea aragonite and it came with a water clarifier which I put in also. The water cleared up in a day or 2 but overtime I try to put a rock in the sand swirls around and then my pump in the refugium blows sand back into the tank covering the rocks and clouding it up again. How can I fix this? I now have sand in the refugium due to this. Please help.
