5 Rules for Adding Calcium Hypochlorite to a Pool

Always pre-dissolve the granules Tossing granules directly into the pool causes bleached liner spots, cloudy water, and undissolved sludge on the bottom.

Fill the bucket with water first Never add water to the granules—that can cause a dangerous chemical reaction. Slowly pour granules into the water while stirring.

Let granules dissolve completely Pour the fully dissolved solution around the pool’s edges while the pump is running.

Add at dusk The sun burns off chlorine quickly. Adding at dusk gives the chemical time to work before UV exposure.

Wear gloves Calcium hypochlorite is strong enough to irritate your skin. Protect your hands every time.
