Fast and easy to use. Dosage instructions included.
Why do I need to use a pH Increaser?
Relax pH Plus will raise the pH level in your hot tub, spa or swimming pool water. A low pH level in hot tub, spa or swimming pool water can cause staining or corrosion, which can damage working parts including pumps, heaters and seals. Low pH levels often also lead to foaming and damage to plastic parts. To prevent this issue, use Relax pH Increaser.
How do I know when pH needs to be raised?
Test the water using pH test strips, if your pH is below 7.2, use pH Plus to bring the pH to between 7.2 and 7.6 on your test kit/strips.
