Both of our local pool stores: Namco & Seasonal Pools don't carry Zeobrite. I can buy it online at www.intheswim.com but I only need 150lbs of sand which would be 75lbs of Zeobrite and they sell it in 50lb bags at $45 each. Is that good price? Would be nice if I could get exactly 75lbs.

Where do you buy your Zeobrite?
