I have never had any of the problems that other sands can cause. It is not as cheap as pool filter sand, but I think is worth the extra and still only runs about as much as gravel.

I bought this sand for my 240 gallon and besides a little dirt (that a few water change vacs took care of, my Motoro stingray is thriving in it with no abrasions on his little underside.
