find a pool supply house and get pool filter sand , its cheap and works great as well as looks good . I've run it in many tanks and playground sand is a bit course for and sharp for some fish
I second this. Pool filter sand is also usually pre-washed, therefore less debris when you add to your tank (or less to wash out if you re-wash before adding to your tank)
right ons, mahalos for all da suggestions =).. just called home depot right now actually and they said they only have sand to mix in cement and its not fish friendly, haha. Asked if they had playground sand too and they dont got =/, bummers.
