Description
Fast-dissolving shock for clearer, cleaner pool water
Poolife Rapid Shock is a fast-dissolving calcium hypochlorite shock treatment that restores chlorine levels and helps clear contaminants from heavy use, storms, or organic buildup. Its stabilizer-free formula adds no cyanuric acid, making it a useful option when you want to shock without adding more pool stabilizer.
The 1 lb size provides one standard dose for 10,000 gallons of pool water. It suits pool owners looking for a single treatment or a convenient size for weekly maintenance.
Restore chlorine after heavy use or storms
Use Rapid Shock as part of weekly maintenance or after rain, heavy swimmer loads, or signs of cloudy water. It helps restore chlorine levels and address contaminants that can affect water clarity.
The product is a 68% calcium hypochlorite formula that quickly eliminates bacteria and algae, as stated in the product details.
Shock without adding cyanuric acid
Rapid Shock is stabilizer-free, so it will not add cyanuric acid or contribute to chlorine lock and over-stabilization.
Because it is a Cal Hypo product, it may slightly increase calcium levels over time. Regular water testing and balancing are recommended.
Fast-dissolving granules, simple application
The granules dissolve quickly and completely when broadcast directly into pool water, with no pre-mixing required. The product details say the formula leaves no cloudy residue.
Apply in the evening with the pump running, distribute evenly across the deep end, and test the water before swimming.
For a range of pool surfaces and systems
Rapid Shock is described as suitable for vinyl, plaster, and fiberglass pools, including in-ground and above-ground pools.
It can also supplement a saltwater system when extra sanitization is needed. The product details also state it is suitable for use with cartridge filters when applied as directed.
