Stable pH. Protected Equipment. Effortlessly Balanced Water.
PoolFlow Alka Boost raises total alkalinity to stabilise your pH, protect your equipment from corrosion and scaling, and help your sanitiser perform at its best. The foundation of balanced water.
Total alkalinity is the foundation of balanced water, the buffer that keeps your pH stable. When alkalinity is too low, pH swings unpredictably, equipment corrodes, surfaces etch, and your sanitiser has to work harder for poorer results.
PoolFlow Alka Boost raises total alkalinity to lock that buffer in place. It’s a fast-acting, fully soluble formula that stabilises pH, protects your equipment from corrosion and scaling, and helps your sanitiser perform at its best. The result is crystal-clear, comfortable water that’s far easier to maintain.
Active ingredient: 100% Sodium Bicarbonate
Suitable for: All pool and spa types, compatible with every sanitising system.
Why Alka Boost Is the Foundation of Balanced Water
Stabilises Your pH. Total alkalinity acts as a buffer, holding your pH steady and preventing the swings that damage equipment and throw your water out of balance. Get this right and everything else gets easier.
Protects Your Equipment. Low alkalinity corrodes spa equipment, including heating elements, and etches surfaces. Alka Boost helps protect your investment by keeping alkalinity in the right range.
Dissolves Fast, No Residue. A 100% soluble formula that acts quickly and won’t cloud your water. Just dose and go.
Gets More From Your Sanitiser. Properly balanced alkalinity makes your sanitiser more effective, so you get cleaner, clearer water with less chemical overall.
Comfortable for Bathers. Balanced alkalinity keeps pH in the comfortable range, helping prevent the eye and skin irritation that comes with poorly balanced water.
Australian Made. Manufactured here in Australia to the same pharmaceutical-grade standards as the full PoolFlow range.
Recommended Range: Maintain total alkalinity between 125-150 ppm for optimal spa water balance.

Application Method:
1. Test water to determine current total alkalinity level
2. Calculate required amount of ALKA BOOST needed
3. Mix measured product in a clean bucket with water
4. Distribute solution evenly around spa with pump running
5. Run filtration system for at least 1 hour to ensure complete distribution
6. Retest water after 4 hours and adjust if necessary
IMPORTANT: If pH has been 6.8 or lower for an extended period and corrosion of metal fixtures is apparent, seek technical advice before adding this product as metal staining may occur.
