What is the best material for the tank bottom – crushed coral or sand? How deep should the substrate be?
Crushed coral, dolomite, or aragonite make an excellent substrate. When used with a good wet-dry and mechanical filter, using approximately one inch in depth is adequate. Other filtering systems may require deeper beds. Very fine sand may enter your pump heads causing severe damage or burn out your pumps.
