I decided to give this a try this year, and I can only say that I am impressed. Our pool has always been clear, but the clarity of the water now is an order of magnitude beyond what it was when we were using sand, and everyone who uses our pool notices it, because of the way the sun hits the pool most of the day it's quite striking because of the patterns made by the sun on the sides and bottom of the pool. I cannot recommend this product highly enough to anyone who is presently using sand.

I can't believe the water clarity using this product. Product gives D.E. filter clarity at a fraction of the cost and provides virtually a maintenance free filtering system.
