Product Overview
What pool techs reach for when water clarity drops, Pool Breeze 68% Cal Hypo reliably handles organic contaminants without increasing stabilizer levels.
Pool techs across the country stock Pool Breeze 68% Cal Hypo Granular because it delivers a concentrated 68% Calcium Hypochlorite dose to effectively sanitize water. This 5 lbs. container (EPA Reg # 1258-161) is a proven choice for breaking down chloramines and clearing algae without the risk of 'chlorine lock' associated with stabilized shocks.

Common Questions & Instructions
How much Pool Breeze 68% Cal Hypo do I need for a 10,000-gallon pool?
For a standard shock treatment, use 1 lb (approximately 16 oz) per 10,000 gallons of pool water to raise the free chlorine level by roughly 8 ppm.
Will this product affect my pool's calcium hardness or pH?
Yes, as a Calcium Hypochlorite product, it will slightly increase calcium hardness and has a high pH, so you should monitor your levels and adjust with muriatic acid if necessary.
When is it safe to swim after using this 5 lbs. shock?
You should wait until the free chlorine residual has dropped to between 1 and 4 ppm, which typically takes 8 to 24 hours depending on the initial load and sunlight exposure.
