Needs lots of rinsing
This item is beautiful in a fish tank. I would have given five stars if they would pre rinse it before bagging. As other reviews stated there is a lot of rinsing that needs to be done before putting it in the tank. After running the filter 24 hours it did clear up. To rinse I used my wife's large strainer from the kitchen and mywater hose.

Great for sump
Great product if you want a sand that won't blow around...the large grains stay put and not in your pump. Does need to be rinsed throughly but that not a negative.
