I love this sand over other sands since you don’t have to wash it and the included water clearing pack had the tank clear within hours after filling it up. Highly recommend
Rinse before you use it. I did not so i had to vacuum the sand bed a couple of times. Setting up a new tank and thought i could add the sand while i was filling the tank. I’m sure if i had rinsed it first it would have been fine. But i must say i love the look. Would use it again.
