DryTec Calcium Hypochlorite Shock Treatment

A 68% concentration is considered a high-strength formula, which provides a rapid chlorine boost to quickly kill bacteria, algae, and organic contaminants. It is significantly more potent than standard maintenance chlorine, making it ideal for clearing up cloudy or green water.

For best results, broadcast the granules evenly across the deepest end of the pool while the pump is running. Avoid pouring it directly into the skimmer, as this can cause a concentrated reaction that may damage your plumbing or filter equipment.

You should wait until the chlorine levels drop back into the safe range, typically between 1 and 4 parts per million (ppm). This usually takes at least 8 to 24 hours depending on your pool's water chemistry and sunlight exposure.

This product is suitable for most standard swimming pools, but you should always dissolve the granules in a bucket of water first if you have a vinyl liner to prevent bleaching or staining. If you have a specialized pool surface, check your manufacturer's guidelines regarding calcium hypochlorite use.

The 1 lb pre-measured bags are designed for convenience and precise dosing, ensuring you don't have to measure out loose chemicals. This format also keeps the remaining product sealed and protected from moisture, which helps maintain the potency of the calcium hypochlorite over time.
