Product Description

Calcium Hypochlorite - Bulk Calcium Super Shock

Our bulk pool shock kills algae, bacteria, and other organic contaminants to quickly turn cloudy pool water clear and clean. It dissolves quickly and uses 68% calcium hypochlorite as the active ingredient to sanitize and help clear even the most contaminated pools.

This versatile granular chlorine calcium hypochlorite, or bulk pool shock, is highly effective for your pool opening in the spring. Its 65% available chlorine gives your swimming pool a quick chlorination boost to keep your pool water crystal clear and free of contaminants throughout the swim season.

Doheny’s bulk pool shock is sold in easy-to-use one-pound bags with a shelf life of up to 18 months, providing a great value for your daily chlorination and pool chemical maintenance needs. The regular dosage is one bag for every 10,000 gallons of water.

Dissolve in water before adding directly into the skimmer or spreading across your pool.

Get rid of harmful contaminants in your water and leave your pool looking crystal clear with Non-Chlorine Oxi-Shock, a powerful chlorine alternative from Doheny’s. Easy on the eyes and skin, non-chlorine pool shock is an effective way to keep your pool or spa clean without the use of harsh chlorine. Safe for any pool surface, the active ingredient, potassium monopersulfate, is a powerful oxidizer that will have your water sparkling all year long! Plus it’s fast-acting so you can start swimming in just 15 minutes. Chlorine-free shock is a great choice for end-of-season pool closing as it won’t bleach surfaces. Doheny’s Non-Chlorine Oxi-Shock is the only shock available that can be used with bromine sanitizer.

How to Use Chlorine Free Shock

To use Doheny’s Non-Chlorine Oxi-Shock in your swimming pool, the recommended dose is 1 pound for every 10,000 gallons of water. For regular maintenance, non-chlorine pool shock should be added weekly. It is also recommended to add at pool opening and closing, after heavy rainfall and after extensive pool use.

In your spa, the recommended dose of Oxi-Shock is 2 ounces for every 300 gallons of water. Chlorine-free shock should be added to the spa after every use, or once a week if it is not being used.
