The SpaChoice Calcium Hardness Increaser is a liquid solution designed to elevate your hot tub experience by increasing water hardness to the ideal level of 200-400 ppm. Each 1-quart bottle effectively raises hardness by approximately 10 ppm per ounce, making it a preferred choice for users seeking convenience and precision over traditional granular products.

Great product
The only thing I dislike about this product is if you have soft water, you have to use quite a bit to get the water balance. Otherwise it works.

Use this every time I fill my hot tub
This works well to get my water into the hardness range recommended by the manufacturer.

Good quality. A bit pricey
Have used for 6 years in my hot tube and now my swim pool.

Just what I needed!
FYI this is liquid not granules. Works like a champ like all leisure time products! Good value and prompt delivery.

Always reliable brand and works great
I have to add a bottle with every drain and refill due to my water softness. Once it’s within range it stays in range. I’ve ordered 3 times and each time works like a charm.

Boost Hardness for Spa
We have pretty soft water naturally, so when I change the water in my spa, I need this. What can you say about a chemical? It is what it is, and does raise the Total Hardness, so no complaints.
