Clorox Pool&Spa Calcium Increaser Pool Water Balancers Granules, 4 lb Bag

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.

Clorox is making these a bit more economical for we spa users. I put the bag contents in a plastic covered tub and keep a teaspoon in it for measuring. This is quite a bit cheaper to use than the Spa labeled competitive brands. You gotta know your spa water volume to get the doses right.

Just what I needed and delivered promptly

I didn't want to use a lot of chemicals in our pool, but after using test strips I needed to increase the hardness. So I bought this and followed the instructions - pretty straightforward and worked to resolve my issue quickly and I had a lot remaining for future use.

It is calcium and does its job of increasing the calcium levels in the pool. The price is good and it comes in a good resealable bag. The instructions are easy to follow as long as you know how much water your pool holds. Like every other calcium product I have tried it does not dissolve very well in a bucket of water before adding it to the pool, but is does seem to dissolve fairly quickly once I pour it in.

I use this product with baking soda and a phosphate remover during the algae bloom of 2026 and within a week my pool was back to Crystal Clearwater

It works as advertised. Not carried inside store for some reason. Of course, I have not checked in a week so....

Found another option because this product didn't raise our levels to what we needed despite using more. Pricey as well.

The bag was open and spilled out.

I did not order this, and have not used it. The gentleman who apparently did my shopping doesn't know the difference between PH and Calcium.
