Dose chlorine granules to reach a target ppm in your pool.
The pool's target level converts to the active chlorine needed, then the product's strength percent increases the dose to grams of product. Pool chemistry needs consistent ppm ranges, and an accurate product dose keeps water safe without wasting chemicals.
Pool Chemical Dose
Active = gallons x ppm x 0.27 / 10,000; product = active / (strength / 100)
Active = gallons x ppm x 0.27 / 10,000; product = active / (strength / 100) The pool's target level converts to the active chlorine needed, then the product's strength percent increases the dose to grams of product.
