Application instructions:

Each tablet weighs approximately 200 grams. For outdoor pools, chlorine residual can be protected from destruction by the sun's rays by adding 300 g of stabilizer (cyanuric acid) per 10,000 L of pool water to yield the required initial concentration of 30 ppm.

If using an automatic chlorinator, fill the chamber(s) with tablets and adjust flow rate, according to manufacturer's recommendations, to maintain proper chlorine residual. Adding tablets to the pool's skimmer basket is an alternative chlorine feed method. Daily usage should approximate 25 g of this product per 10,000 L of pool water.

Note:

Hot weather, heavy pool usage, and rain may require higher usage rates to maintain proper chlorine residuals. This product contains stabilizer which can accumulate in pool water. Keep stabilizer within the range of 30-100 ppm by dilution of fresh water. DO NOT enter pool until the free available chlorine residual is 1-3 ppm.
