Pool Shocks – Shock Treatments for Clean Pools

Nothing beats the confidence of stepping into crystal-clear water. A reliable pool shock treatment is the foundation of that clarity, eliminating contaminants that regular chlorine maintenance can miss. Whether you are opening your pool for the season, recovering from a heavy swim day, or battling stubborn algae, the right shock restores your water to its sparkling best. At PST Pool Supplies, we carry a focused selection of shock products from brands you can trust, including DuraChlor, Solenis, Qualco, and Pool Season.

Our lineup includes both chlorine pool shock and non-chlorine shock oxidizer options so you can match the treatment to your specific needs. High-strength dichlor formulas like Qualco Instant Shock 99% and DuraChlor Quick Shock 56% deliver fast-acting sanitation that destroys bacteria and organic waste on contact. For routine oxidation without raising chlorine levels, non-chlorine alternatives such as the Shoxidizer Shock and Pool Season Non-Chlorine Shock Oxidizer break down combined chlorine and restore water clarity without the wait time before swimming. If you need to test and balance your water before or after treatment, check out our pool test kits for accurate results every time.

Granular pool shock products like DuraChlor Assault 73 and Assault 68 offer calcium hypochlorite-based power that is ideal for weekly maintenance and algae prevention. DuraChlor Multishock Extra 35% combines shocking, clarifying, and algae-fighting action in a single step, simplifying your pool care routine. Proper shock treatment is an essential part of safe recreational water maintenance, as recommended by the CDC's healthy swimming guidelines. When handling any pool chemical, always follow the product label and the safety practices outlined by the EPA's safe pesticide and chemical use resources. Browse our full range of pool chemicals to build a complete maintenance program.

Find the right pool shock treatment for your water below and enjoy a cleaner, healthier pool all season long. Every product ships from Idaho Falls with the personalized service PST Pool Supplies is known for.

Frequently Asked Questions

What is pool shock and why do I need it?
Pool shock is a concentrated dose of chemicals—either chlorine-based or non-chlorine—that rapidly raises the sanitizer level in your water. Shocking your pool breaks down chloramines (the compounds that cause that harsh "chlorine smell"), kills bacteria and algae, and restores water clarity. It's one of the most important steps in routine pool chemical maintenance, especially after heavy use, rainstorms, or when your water starts looking dull or hazy.
What's the difference between chlorine and non-chlorine pool shock?
Chlorine shock, like our DuraChlor Assault 73 or Quick Shock 56% Dichlor, adds active chlorine to sanitize and kill algae. It's the best choice when you need to eliminate a visible algae bloom or serious contamination. Non-chlorine shock oxidizers, such as the Shoxidizer or Pool Season Non-Chlorine Shock, break down organic waste and restore water clarity without raising chlorine levels. The biggest advantage of non-chlorine shock is that you can swim again in as little as 15 minutes after treatment.
How often should I shock my pool?
For most residential pools, shocking once a week during swimming season keeps your water balanced and clear. You should also shock after pool parties, heavy rain, or any time your water test results show high combined chlorine (above 0.3 ppm). If you notice cloudy water, a strong chlorine odor, or early signs of algae growth, don't wait—shock right away. Consistent shocking prevents small water quality issues from turning into bigger, more expensive problems.
How do I apply granular pool shock correctly?
Always shock your pool in the evening or at night, since sunlight breaks down chlorine quickly. Pre-dissolve granular shock in a bucket of warm water before adding it to your pool—this prevents bleaching your liner and helps it distribute evenly. Pour the solution around the perimeter of the pool with your pump running. Never mix different shock products together, and always follow the dosage instructions on the label based on your pool's volume. Run your pool pump for at least 8 hours after treatment.
How long after shocking my pool can I swim?
With non-chlorine shock, you can typically swim within 15 to 20 minutes once the product has fully dissolved and circulated. For chlorine-based shock treatments, you'll need to wait until your free chlorine level drops back to 5 ppm or below—usually 8 to 24 hours depending on the dose and sunlight exposure. Always test your water with test strips or a test kit before jumping back in to be safe.
