ShadowStryder;1134098; said:I personally like gravel. When I vacuum my tank I vacuum the whole substrate anyway so I don't worry about dead spots. If you keep multiple large cichlids in a tank with sand the wast can be unsitely floating around on top of the sand. Plus you must put your intakes ( I use XP4s on 125) higher off the substrate so as not to draw sand into the impeller and ruin it.
Plus I like black, I believe it makes the colors pop.
In the end it is a personal preference. Your tank, Your taste.
