SpaGuard Total Alkalinity Increaser
I've been using this on my Marquis spa for 3 years and been satisfied with it. |

Really works!
When I first got my new spa this was included but I didn't use it at first and I kept adding ph up and ph down products every day or so. Then I used this and now I infrequently have to add the other products and the ph is in the ideal range most of the time! |
