Poolife Rapid Shock: 68% Cal-Hypo pool shock for weekly maintenance
Use Rapid Shock every 7 days, or as necessary to help prevent pool problems. The label directs users to add 1 bag per 10,000 gallons of water for shock treatment or superchlorination.
The label also identifies visible algae, high bathing loads, heavy wind and rainstorms, unpleasant odors, and eye irritation as conditions that may require shock treatment. Check available chlorine with a suitable test kit.
Fast-dissolving pool shock with no added CYA
Rapid Shock is a 68% calcium hypochlorite formula that adds no cyanuric acid (CYA). It is a stabilizer-free option when you want to shock without adding more pool stabilizer.
As a Cal Hypo product, it may slightly increase calcium levels over time. Test and balance pool water regularly.
How to add Rapid Shock granules
Do not pre-mix. Add the product directly to the pool during evening hours while the filter pump is running, broadcasting it evenly over a wide area in the deepest part of the pool.
If granules settle on the pool bottom, use a brush to disperse them. Use the entire contents of a bag once opened, and check free available chlorine before swimming.
Pool surfaces and system compatibility
Rapid Shock is described as suitable for vinyl, plaster, and fiberglass pools, including in-ground and above-ground pools. Product details also state that it is suitable for cartridge filters when applied as directed.
It can supplement a saltwater system when extra sanitization is needed. The label warns not to mix Rapid Shock with other water-treatment products; follow the product label and your system instructions.
Balance water and troubleshoot pool problems
For best product performance, swimmer comfort, and clear water, the label recommends pH of 7.2–7.6, total alkalinity of 60–120 ppm, and calcium hardness above 200 ppm. Use a reliable test kit to check these ranges.
For visible algae, odors, eye irritation, or problems after heavy bathing loads or storms, check available chlorine and follow the container directions for any additional shock treatment.
