Pure Pool pH Buffer – Pure Pool Products
Achieve stable, swimmer-safe water with Pure Pool pH Buffer. This sodium bicarbonate-based formula is designed to raise and maintain your pool’s total alkalinity, helping to prevent pH swings and keep your water balanced, clear, and gentle on skin, eyes, and equipment.
Why Pool Owners Love pH Buffer
Raises total alkalinity to stabilise pH and prevent wild fluctuations
Helps prevent corrosion, surface damage, and cloudy water
Easy-to-use, fine-grade powder dissolves quickly with no residue
Essential for all pool types, especially those exposed to rain, heavy use, or acid treatments
Compatible with chlorine, saltwater, and mineral pools
Packaged in moisture-resistant, resealable bags for safe, long-term storage
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.
Why Choose pH Buffer Over Generic Baking Soda?
Specifically formulated for pool use—more consistent, more effective
Better solubility and particle size for faster dissolving
Guaranteed chemical purity for reliable results every time
Packaged and labelled for safe storage and easy use

Cal-Up – Pure Pool Products
Protect your pool surface and equipment with Pure Pool Cal-Up, a fast-acting calcium hardness increaser made from high-purity calcium chloride. Designed to restore and maintain the right total hardness levels in your water, Cal-Up helps prevent long-term damage—keeping your pool in perfect shape all season long.
Why Pool Owners Love Cal-Up
Quickly increases calcium hardness levels to protect your pool surface
Prevents etching, corrosion, and equipment wear caused by soft or aggressive water
High-purity formula dissolves fast—no residue or clouding
Essential for concrete, tiled, or plaster pools prone to surface damage
Helps balance water chemistry as part of a complete maintenance routine
Available in convenient, resealable packaging for easy storage and use
Why Calcium Hardness Matters
When your pool water is too soft (low in calcium), it becomes aggressive—meaning it will draw minerals from your pool surface or equipment to balance itself. This leads to pitting, etching, and corrosion over time. Pure Pool Cal-Up prevents this by safely raising calcium levels, keeping your pool water balanced and non-destructive.
How It Works
Pure Pool Cal-Up is a calcium chloride-based compound that dissolves rapidly in water, boosting total hardness levels in just a few hours. By increasing calcium levels to the ideal range (between 200–400 ppm), it helps create stable water that won’t damage your surfaces, fixtures, or filters.
Dosage Guide
To raise hardness by 10 ppm: Add 100g per 10,000 litres of water
Typical application: 1–2kg for standard pools with low calcium levels
Always test water hardness before dosing, and adjust as needed
Broadcast directly into the deep end or pre-dissolve in a bucket before adding
Pro Tip: Add Cal-Up while the pump is running to ensure even distribution and faster dissolving.
Safe for All Pool Types
Cal-Up is safe to use in concrete, pebblecrete, fiberglass, and vinyl-lined pools. It's especially important for concrete and tiled pools, where low calcium can cause visible surface damage. Compatible with all filtration systems when used as directed.
So Simple to Use
Just measure the required amount, broadcast it directly into the pool, or pre-dissolve in a bucket of water for a gentler application. With fast-acting, low-dust granules, there’s no mess—just balanced, protected water in no time.
Why Choose Cal-Up Over Other Hardness Increasers?
Superior purity for quicker dissolving and fewer residues
Doesn’t cloud water or interfere with other chemicals
Long shelf life in sealed, moisture-resistant packaging
Trusted by pool professionals and home users alike
