i finally tracked down the lfs that sold me the sand i used to have in my old ray tank before moving out of state. he told me that i should be looking for "round sand" . i bought a 100 lbs bag of silica sand from a construction supply co. and even though ti's better than play snd it's no where as natural looking and as coarsed as the one i used to have , does anyone know what round sand is and where to get them? here's a picture of what i used to have
