Protects the Vinyl Liner
I use the Clorox Calcium hardness increaser to protect our vinyl pool liner. It dissolves quickly and is effective in increasing the transparency of the water and reducing algae blooms.

Great value for a needed product
This hardness increase works every bit as well as the premium products from a fancy spa supply house. Name brand product, great value, easily applied and with two internal packages, useful for a good long time. I did admittedly transfer this product to a sturdy plastic canister for better moisture protection and easier storage / application. Would easily recommend and will certainly order again.

Great product
I used this in my hot tub to harden the city water. Worked just as good as the expensive stuff from there and was bigger volume in bag verses their little bottle of it.

Works
You can get better chemicals. I feel like you have to use a extra amount to get the job done. But it will get the job done.
