Anyone ever use High Dessert Play Sand in their tank?

[Savas]

The sand is a beautiful white color and resembles what I call sugar sand - fine grain. I just bought some for my daughters sand box and am thinking of using it in my tank to fill in some open areas where some crushed coral has risen to the top of the tank.

Any thoughts are appreciated.

If its from HD and made by Paverstone its not reef safe. It is a silica based sand. I got 150lbs in my truck to return right now
