Know before you buy
A non-stabilized shock like this one does not contain cyanuric acid, which allows you to raise your chlorine levels quickly without the risk of over-stabilizing your pool. This makes it an excellent choice for rapid sanitization, such as clearing up algae blooms or preparing your pool for the season.
The standard dosage is 1 pound of granules per 10,000 gallons of water. Always ensure your pump is running to help distribute the product evenly throughout the pool.
Yes. That distinct chemical smell is often caused by chloramines, which are byproducts of chlorine working against contaminants. This shock effectively breaks down those chloramines to restore water clarity and reduce skin and eye irritation.
Absolutely. While it is powerful enough for heavy-duty tasks like spring openings or algae treatment, it is also effective for routine weekly maintenance to keep your water balanced and sanitized.
For best results, broadcast the granules evenly across the surface of the water, ideally in the evening when the sun is down. This prevents the chlorine from being degraded by UV rays before it has a chance to work.
This is a calcium hypochlorite-based shock, which is suitable for most standard swimming pools. However, if you have a vinyl liner, it is best to dissolve the granules in a bucket of water first to ensure they don't settle on the floor and cause bleaching.
