So after reading some posts, I made up my mind to use pool filter sand for my new set up. Then I called a pool supply store to make sure they had some. He said, sure, we've got silica. Now I remember reading somewhere that silica is abrasive on rays...but several of you use it. Please settle this for me. Is pool filter sand really ok for our rays?
