Easy Way to Balance Pool Water
This calcium hardness increaser worked exactly as expected. It dissolved well, was easy to add to my pool, and helped bring my calcium hardness into the proper range without any issues. After using it, my pool water stayed balanced, and I felt confident knowing I was helping protect my pool surfaces and equipment. It's an excellent product that's simple to use and does what it promises. I would definitely purchase it again.

Better Product
I especially like the quality of this calcium product. It disperses in very small beads and is absorbed very quickly into the pool water. Faster product than the crystal calcium’s.
