Clorox pool chemicals
I started buying Clorox pool chemicals because of the quick and free delivery, after using them last year my water stayed just as clean and clear as when I used the expensive pool store products, so far have used the stabilizer,, algecide, hardness increaser and ph products with good results. will continue to buy from Walmart and start building my summer supply.
