Been researching this a lot, and see many people agree sand is the best substrate. I want to keep corys in my new community tank too, so they'd be happier. What I want to do, though, is use a dark sand, such as black sand. what's the best type? Not worried about plant food stored because I will use liquid food plus pellent food for the rooting varieties, (although if there is a black sand which incorporates nutrients all well and good).
