I've had many tanks in the past and I'm just now setting them back up.....I had them in storage for the last couple years, I've been moving around and working on the road. Anyways I've always just ran with the regular gravel in all of my tanks I'm setting up a chiclid tank and saw a sand that says it actually particularly for chiclid tanks. Does anyone know if running with the sand will promote my tank much more than your normal gravel. I was planning on running an underground filter(which I know everyone says you dont need, but I still like running with one)in which would make it almost impossible to run with the sand. I'm also running a magnum 350 in which the UG filter is not my only filter on the tank. I still like using the UG filters with my power heads and it seems like it makes clean up a breeze when it's time to get out the gravel vac. Any suggestions ????
