Someone local has some black sand to sell, but he says it has dafnia, worms and scuds in it. He says that is a good thing. It is only enough for a thin layer in my 60 gallon so i will have to cap it with something or use it as the cap. Is this something i should bother with? Can i plant anubias directly into this? Also, i read somewhere that sand can build up pockets of some type of toxic gas or something. How is this prevented?
