• Dosage Charts

    If you know how many gallons you have in your pool (Unsure of your gallons see this calculator: (POOL VOLUME CALCULATOR) these charts will take the guess work out of "how much" of anything to add. Always read the manufactures label as their instructions take precedence over these general guide lines. Always use caution when adding over 12 lbs. of any pool product at once. when adding acid take caution not to stain your surface and or corrode heaters etc.

  • Lets Start With 12.5% HASA Liquid Chlorine. 10 PPM Is Shocking Your Pool

    Keep you FC at 3 ppm and when it falls below 2 ppm add a little to bump it up to 3 ppm again. If you can check every Wednesday & Sunday you should be able to prevent shocking all together.
