pH/Alk Down pH & Alkalinity Decreaser by FreshWater

$ 13.99

Adjust your hot tub's pH & your Alkalinity down with this. You'll want to adjust pH first, never adding more than 1 ounce at at time. Give pH about 24 hours/one day to settle in before adding anymore adjuster. Then you can adjust your Alkalinity, hardness, and sanitizer.
