Effective Pool Shock Treatments for Clean, Clear Water

Keeping your pool water pristine and safe requires regular shock treatments to eliminate bacteria, algae, and organic contaminants that everyday chlorine can’t always handle. Whether you have an inground or above ground pool, Doheny’s professional-grade pool shocks deliver powerful cleaning and oxidation to restore clarity and freshness all season long.

Calcium Hypochlorite Shock (Cal-Hypo) is a fast-acting, granular chlorine shock widely used for tackling tough algae blooms and heavily contaminated pools. Also called super shock, it boosts chlorine levels quickly and effectively removes bacteria and algae. Doheny’s Super Shock contains 68% calcium hypochlorite, making it one of the most powerful chlorine shocks available.

Di-Chlor Shock combines chlorine with cyanuric acid in a stabilized granular formula that protects it from sunlight degradation. It’s gentle on vinyl liners and delicate surfaces, making it a great choice for pools with vinyl, fiberglass, or colored plaster finishes. Di-Chlor also lowers pH slightly, so you may need to balance your pool chemistry after use. It works well with saltwater and liquid chlorine pools.

Oxidizing Shock (Non-Chlorine Shock) is a chlorine-free alternative designed to oxidize contaminants without irritating skin or eyes. It allows you to swim just 15 minutes after treatment and is perfect for weekly maintenance alongside traditional chlorine shock to keep your pool sparkling clear and comfortable for swimmers.

Pool Shock FAQs

How much pool shock should I use?

For all Doheny’s professional pool shocks, the standard dosage is 1 lb per 10,000 gallons. In cases of algae outbreaks, double the amount to 2 lbs per 10,000 gallons for a deeper clean.

Which pool shock is right for my pool?

Your choice depends on pool type, surface, and sanitizer system. For more details, check out our detailed guide to different types of pool shock.

When is the best time to shock my pool?

Shock your pool weekly or as needed—especially after heavy use, storms, or when algae appears. For best results, apply shock treatments at night to prevent UV sunlight from reducing effectiveness, allowing you to swim safely by morning.

Is it safe to swim after shocking my pool?

For most chlorine-based shocks, wait 12 to 24 hours until chlorine levels return to normal to avoid irritation. Non-chlorine oxidizing shock lets you swim just 15 minutes after treatment.

How can I tell if my shock treatment worked?

Test free chlorine levels to confirm they’ve risen and stabilized. You should also notice reduced chloramine odor and clearer water as contaminants break down.

Why is my pool still cloudy after shocking?

Your filter may need to run 24-48 hours to clear debris. Vacuuming dead algae and balancing your pool’s chemical levels can also help. Incorrect shock dosages or poor circulation might cause lingering cloudiness.

How do I store pool shock safely?

Proper storage is crucial to safety and product effectiveness. Learn the best practices in our pool chemical storage guide.
