Pool pH Increaser

Pool pH increaser (soda ash or sodium carbonate) is used to raise the pH level of swimming pool water. The pool pH should be maintained at 7.2-7.6 for optimum chlorine or sanitizer activity and best water quality. Proper pool pH (potential hydrogen) is one of the most important factors of pool water balance and routine pool maintenance.

Pool pH increaser is also known as pH Plus and pH Up, depending on where you live geographically and which product brands are being sold in your area.

Pool pH increaser may be used for any pool or spa. Adding pH increaser to pool or spa water slows the rapid loss of chlorine caused by the pH being too low. It will raise the pH to slow pool water chlorine dissipation, so your pool or spa uses less chlorine. A low pH level may cause eye irritation, corrode metal fixtures, cause pool etching, staining, shorten pool liner life and other problems.

pH Increaser is compatible with and just as effective as Baquacil®, Soft Swim® and Revacil® biguanide pool chemicals too.

Recommended dosage: To raise pool pH, distribute a maximum of 1 Lb of pool pH increaser per 10,000 gallons of water directly into the deep end of the pool. Allow water to recirculate two to three hours, recheck and adjust further if necessary.
