so called "aquatic" sand is merely another sales gimmick to get punters to part with much more cash than they have to .
as long as the water you are washing the sand in is virtually clear playsand is great but ive fopund it needs to be aggitated every couple of weeks or so otherwise it gets harmfull gas pockets and turns black and stagnent smelly but ive got it 5" deep at the back and 2" at the front
You should get some silicate remover for your filter medium if ur going to use cheap sand
