I'm setting up a new 46 gallon glass bowfront, and want to use sand as the substrate. In the past, I've used swimming pool filter sand. But I have that in my 16 gallon, and the top layer is turning dark brown. Are there better sands out there? PetSmart sells National Geographic brand sand, but it's $20 per 25lb bag. Is it really that much better?
