Why You'll Love It
- Destroys Contaminants — Effectively breaks down organic waste, sweat, and oils that cause dull water and eye irritation.
- No Stabilizer Buildup — Since this formula contains no cyanuric acid (CYA), it won't over-stabilize your pool even with frequent use.
- Fast Dissolving Rate — The granular formula is designed to dissolve quickly in the water column to start working on bacteria and algae immediately.
- Crystal Clear Results — Regular use helps prevent algae blooms and clears up cloudy water by boosting your free chlorine residual.
Best For
- Weekly maintenance doses
- Treating green or cloudy water
- Opening pools in the spring
- Vinyl, plaster, and fiberglass pools
How to Use
- Test water and ensure pH is between 7.2 and 7.4 for maximum effectiveness.
- With the pump running, broadcast the granules evenly over the deep end.
- Pre-dissolve in a bucket of water first if you have a vinyl liner to prevent bleaching.
- Wait for chlorine levels to drop below 4ppm before allowing swimmers back in.
Pro Tip
Always shock your pool at dusk or night; the sun's UV rays can burn off unstabilized chlorine in just a few hours, wasting your treatment.
Always follow label directions. Test and balance water chemistry before and after treatment. Keep chemicals stored sealed, cool, and dry.
