Product Description

PH Plus is used for increasing the PH level in your hot tub, spa or swimming pool. A low PH level in a pool or hot tub water can cause foaming and long term damage to plastic parts of the tub. To prevent this issue, use PH Plus to bring the PH to between 7.2 and 7.4 on your test kit/strips. 5Kg Castle Hot Tubs PH Up Increaser - white
