I've read alot that people are using fine sand for their freshwater aquariums now. Supposedly it is easier to maintain from a waste perspective, as most of the crap either sits on the surface, or gets taken away from the "current" into the filter. I have used play sand from Home Depot in many of the salt water aquariums, and was very pleased. Can this same product be used in an aquarium with small cichlids and live plants?
