Alkalinity Increaser 1KG + 50 Water Test Strips

The Ultimate pH Stabiliser
Low TA makes your pH level swing wildly, causing endless maintenance headaches. Our Alkalinity Increaser creates a powerful buffer so your pH stays put, saving you time and worry.

Protect Your Investment
Highly acidic water (caused by low TA) can be aggressive, slowly corroding your expensive pumps, heaters, and jets. Protect your spa's vital components by maintaining a stable TA level.

Say Goodbye to Irritation
When your pH is unstable, your water can become irritating to the eyes and skin. Properly buffered water ensures a soothing, comfortable, and truly relaxing soak every time.

Boost Sanitiser Power
Your chlorine and bromine work best when the pH is perfectly balanced (pH 7.2 – 7.6). By stabilising your water, this product allows your sanitiser to function at maximum efficiency, keeping your water safer and cleaner.

Fast & Easy to Use
The quick-dissolving granular formula ensures rapid integration into your water. Simply pre-dissolve and add, you’ll be ready to soak again in no time!

Ideal TA Range
100 – 140 ppm

Dose
Add ≈160g per 1,000L to increase TA by 10ppm.

Safety Disclaimer
