Alkalinity & pH Up - 1 lb.

I test the chemical levels in my spa and sometimes the alkaline level is fine but the ph is low or vice a versa. I would rather purchase them separately.

Came fast and it’s exactly what I ordered.

I have used Spadepot for years with my hot tub. PH up balances my water quickly. It works great.

Works as advertised.. good price.. very satisfied.

do not use often. dissolves quickly. works.
