I use sugar sized play sand in all aquariums. plants root better and fish are
able to interact in a more natural way with sand than they are with gravel.
Don't worry about build up of gasses under the sand. it's not as big a problem
as they hype would lead you to believe.
remove nospam from e-mail to send to me, I grow trees in aquariums like bonsai.
I breed dwarf crayfish, great for planted community tanks. If you can get me a
shovelnose sturgeon fingerling (Scaphirhynchus platorynchus) no wild caught
please, contact me
