SpaGuard pH Increaser 1.12lb Granular Spa Hot Tub pH Balancer

I rarely need pH increaser, as my tub tends to rise in pH, but I've found this to be effective when I've needed it.

This is a great-quality pH increaser that dissolves quickly and works exactly as intended. It raises the pH efficiently without leaving residue behind. A solid, dependable choice for maintaining balanced spa water.

Easy to use and worked just fine.

It increases pH. Is it better than baking soda? I don’t know, but it makes me feel good.

This product is very easy to use. One simply measure the desired amount and pour it into the spa while the circulation pump is running.
