Flow vs Sand
I plan on having a large amount of flow in my 180G I'm about to set up. Right now I've got two Mag 36's. One for a return pump and one for a closed loop. Is there any chance I can get sand or any kind of finer substrate other than crushed coral chunks in the tank with this amount of flow? I really want an inch or two or sand just for the natural look really.
