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.

Can use as a refill

You can also use this to refill your damprid containers - it's the same thing. Just be sure to keep the package closed and in a dry location.

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
