Product Details

What is Clearwater® pH Plus for?

ClearWater pH Plus is the best way to increase a hot tub's pH levels if it falls lower than 7.3.

Incorrect pH and Total Alkalinity levels can impact the water quality and the experience for the user and results in chlorine imbalances.

The recommended pH balance is between 7.2 and 7.6. When pH levels drop below 7.2 acidity increases and pH increaser is needed.

How does Clearwater pH work?

ClearWater pH Plus is a chemical component that introduces alkaline substances into the water, neutralising acidic components and raising the pH.

Clearwater pH Plus - Quick Start Guide

Step 1: Test water. If pH levels are lower than 7.2, use pH Plus

Step 2: Measure the quantity you need (refer to the label). 1g of pH minus per 100L of water to lower pH by 0.1

Step 3: Dissolve pH granules in a container of warm water. Pour dissolved mixture into the hot tub.

Step 4: Run the filter and leave for 4hrs. Retest and repeat if needed.

As with all chemical products, time should be taken carefully read through instructions and warnings before using.
