What pH Buffer Actually Does
Your pool’s total alkalinity acts as a buffer for pH. When alkalinity is too low, pH levels can swing up and down unpredictably—leading to irritation, corrosion, or cloudy water. Pure Pool pH Buffer safely raises alkalinity, stabilising your pool’s chemistry and making pH easier to manage long term.
How It Works
Pure Pool pH Buffer is made from high-quality sodium bicarbonate, which increases total alkalinity without raising pH too dramatically. Once added, it helps “lock in” your desired pH range—reducing the need for frequent chemical adjustments.
Dosage Guide
To raise alkalinity by 10 ppm: Add 180g per 10,000 litres of water
Typical starting dose: 1–3 kg, depending on test results
Always test total alkalinity before dosing and aim for a range of 80–120 ppm
Broadcast directly across the pool surface with pump running
Pro Tip: Adjust alkalinity first, then fine-tune pH with acid or pH increaser if needed.
Safe for All Pool Types
Pure Pool pH Buffer is suitable for use in all pool types and surfaces, including concrete, fiberglass, vinyl, and pebblecrete. It’s also compatible with all filtration systems and sanitiser types when used as directed.
So Simple to Use
No premixing needed. Just measure, broadcast evenly into the pool, and let your circulation system do the rest. The fast-dissolving formula means no mess, no clouding—just beautifully balanced water.
