Works as described.
Works good in an 8 x 8 spa. I didn't realize my water was actually too soft for a spa, but this does the trick.

Increases Water Hardness.
Increases hardness of water. I should probably buy a bigger size container or stock up on these. I probably needed 2/3 of the container to get the water where I wanted it for my tub. But it does what it is supposed to.

Easy to use for small pool or spa
Not large enough bottle for use in larger pools or swim spas

Just calcium chloride
Needed some salt as I used reclaimed rain water for my spa. Just calcium chloride, works great. They maybe cheaper ways to buy calcium chloride
