Pool Boss Alka-Plus raises the total alkalinity in your spa and acts as a pH stabilizer. Alka-Plus will also help to raise your pH at the same time. The ideal level of total alkalinity is between 80-180 ppm.

It is important to note that a low total alkalinity will cause your pH to wander and promote corrosive water. Total alkalinity should always be balanced before adjusting pH levels.

We recommend to test regularly and adjust especially when fresh water is added.
