Overview

Pool Protector’s Hardness Increaser is a premium calcium booster designed to maintain the correct hardness level in your pool or spa. Balanced calcium hardness is essential for preserving the integrity of pool surfaces and internal plumbing.

How It Works

Low calcium levels in pool water can cause aggressive water conditions, leading to corrosion, etching, and surface damage. This fast-dissolving granular product increases calcium hardness to recommended levels, helping extend the life of pool finishes and equipment.

This 2kg hardness increaser is ideal for:

• Concrete, fibreglass, vinyl, and tiled pools

• Spa pools with low calcium readings

• Use after heavy rainfall or water dilution

Directions for Use

1. Test pool water for calcium hardness levels.

2. Calculate required dosage to reach ideal range (200–400 ppm).

3. With the pump running, slowly add product to deep end of the pool.

4. Allow water to circulate for 4–6 hours.
