    • Effective, easy to use & inexpensive!
Size: 1 Count (Pack of 1)
Instead of traipsing to our close to home Leslie's pool store for fast convenience, I'm happy to have bought this on Amazon. Works like a charm & much cheaper! I don't usually handle pool chems (husband does), but this is easy peasy.

Size: 1 Count (Pack of 1)
It’s sodium carbonate, baking soda, why pay more than the minimum for the same thing with a fancy label? Makes no sense. This is 100%, nicely granulated, flows well, no caking noticed. For convenience I refill the original plastic container that came with the spa starter kit. FWIW, I’ve found all the Clorox spa products to be most cost effective compared to the competition, so far. ... show more
