When To Use This
Pro Tip
In hard water regions like the Southwest, continuous use of Cal Hypo can push your calcium hardness past the ideal 200–400 ppm range. If your calcium levels are climbing, alternate this product with liquid chlorine to prevent scale formation on your pool surfaces and equipment.
Common Questions & Instructions
How much Pool Breeze granular 68 do I need to shock my pool?
For standard shock treatment, add 1 lb of Pool Breeze granular 68 per 10,000 gallons of pool water to raise free chlorine levels. If you are dealing with severe algae or a green pool, you may need to double the dose to 2 lbs per 10,000 gallons. Always test your water first to ensure pH is between 7.2–7.6.
Does Pool Breeze 68% Cal Hypo shock raise calcium hardness?
Yes, because it is a calcium hypochlorite-based shock, it will introduce a small amount of calcium to your water (about 0.8 ppm per pound per 10,000 gallons). If your calcium hardness is already near or above the ideal 200–400 ppm range, monitor your levels closely to avoid scaling.
How long should I wait to swim after using Pool Breeze Cal Hypo?
You should wait to swim until the free chlorine level has dropped back down to the ideal range of 1–3 ppm. This typically takes 8 to 24 hours depending on sunlight, water temperature, and the initial organic load in the pool.
