Protects pool equipment from corrosion.
Prevents staining, plaster etching, or liner wrinkling.
What's in it:
100% sodium hydrogen carbonate (also known as sodium bicarbonate).
How to use it:
Test your pool water's total alkalinity.
Add the required amount directly to the pool water with the pump running.
Brush any undissolved granules off the pool surface.
Ideal total alkalinity range:
125–150 mg/L (ppm).
Safety tips:
Wear gloves and eye protection.
