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.

Works as described!

This was great. I poured it into my pool to get the calcium up and it worked. Make sure to follow the directions on the bag exactly as you should. The Ease Of Use was very simple.
