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.

It's important to keep your calcium levels up

Does what it's supposed to do. When I need more than 10 pounds I tried to buy the bigger bags online

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. You can use a bucket to dissolve it in first 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.
