So I've been a gravel user in my aquariums since I began the hobby. I bought some aquarium sand months ago, but never got around to using it. So my question to you all is, would you all recommend sand over gravel in an ACF aquarium, and if so, how much sand should I put in there? I'm erring on the side of caution because I know that the frogs can kick up all kinds of debris and I have heard that sand can mess up power filters pretty bad. What do you all suggest?
