I am just starting at salt water fish and coral. I have a under water filter with two jets and and external filter as well. Because of the underwater filter I had to go with crushed coral instead of sand. My questions is what kind of clean up crew should I go with? Its a 55 gal, with some live rock, and crushed coral instead of sand. Also how big of a role does the crushed coral play in things; like what would be ok in a sand but not crushed coral?
