Why You'll Love It
- Rapid Sanitizing Power — The high-strength formula works quickly to kill bacteria and clear up cloudy water conditions.
- Cyanuric Acid Free — Being non-stabilized, this shock will not raise your stabilizer (CYA) levels, helping you keep your water chemistry in balance.
- Pre-Measured Convenience — The 1lb bags eliminate the need for measuring cups, making it easy to apply the exact dosage your pool requires.
- Algae Treatment — Effective at breaking down resistant algae and organic waste that can build up during the peak of the Long Island summer.
Best For
- Weekly maintenance doses
- Treating green or cloudy water
- Opening pools in the spring
- Post-storm water recovery
How to Use
- Test water and adjust pH to 7.2–7.6 for maximum effectiveness.
- Run the filter system and broadcast the granules directly into the deep end.
- Use 1lb per 10,000 gallons for normal shocking, or more for heavy algae.
- Wait for chlorine levels to drop below 4 ppm before swimming.
Pro Tip
Always shock your pool at dusk or night; the sun's UV rays break down un-stabilized chlorine quickly, so applying it after dark ensures the chemical works longer on your water.
Always follow label directions. Test and balance water chemistry before and after treatment. Keep chemicals stored sealed, cool, and dry.
