Pool Mate 25-Pounds Premium Calcium Hardness Increaser for Pools

Works good

Works perfectly. Saves me a ton of money, compared to Leslie’s pools pricing. Chemical works perfectly when you follow the directions. I add my chemicals at night personally for maximum effectiveness. Comes in a cardboard box with product in a plastic bag. I transfer it to the sealed bucket that I purchased long ago from Leslie’s and it’s still perfectly effective the following year.

Good product, flaky calcium chloride. Good price. Dissolves quickly with no visible residue. I am satisfied. Thanks. A+

My pool was low, mixed it in a 5 gallon bucket and ran the pool for 4 hours to mix. It brought the level up to 300.

Worked good

If your pool needs calcium this definitely a trusted brand. Works as it should.

These calcium chloride flakes dissolve quickly and are easy to use. They are contained in a well labeled heavy plastic bag with integrated handle. Instructions for use are straightforward and easy to understand.
