DuraChlor Pool Chemicals

Keep your pool crystal clear all season with DuraChlor pool chemicals — a trusted, complete pool care system designed to handle every aspect of water maintenance. PST Pool Supplies carries the full DuraChlor product line, from sanitizers and shocks to algaecides, water balance products, and specialty treatments — starting from $19.10. Whether you are opening your pool for summer or closing it for winter, DuraChlor pool care products give you everything you need in one reliable brand.

The DuraChlor system is built around six keys to pool care: Clean, Activate, Balance, Reduce, Sanitize, and Shock. At the heart of the lineup is DuraChlor Activator — a unique product you add once at the beginning of the season that enhances water quality, improves filtration efficiency, helps control algae, reduces eye and skin irritation, and prevents staining. For daily sanitization, you can choose from high-compression DuraChlor chlorine tablets that dissolve slowly for consistent chlorine levels, ultra-fast dissolving granular chlorine, or Ultra Brom for pools that need a chlorine alternative. When your water needs a boost, the DuraChlor pool shock range covers every situation — Wipe Out non-chlorine shock restores clarity without raising chlorine levels, Assault 73 delivers low-residue treatment, Quick Shock acts fast, and Multi Shock Extra provides a buffered shock treatment for weekly maintenance.

Algae prevention and removal are covered by a deep lineup of DuraChlor algaecide products, including Combat 60 polyquat algaecide, copper-based Algae Kil Cb7, and Mustard Eliminator for stubborn yellow algae. Water balance essentials — pH Up, pH Down, Alkalinity Increaser, Hardness Increaser, Stabilizer, and Chlor Out — help you maintain ideal ranges (pH 7.2–7.6, total alkalinity 80–120 ppm, calcium hardness 200–400 ppm). Stain and scale products like Rust-N-Scale, Metal Wizard, and Stain Eliminator protect your pool surfaces, while specialty items such as Phosphate Away, Filter Cleaner, and seasonal Opening and Closing Kits round out the collection. DuraChlor supports both a traditional care program and a low chlorine program — learn more at the official DuraChlor Pool website or review EPA pool chemical safety guidelines for best practices.

Shop DuraChlor pool chemicals at PST Pool Supplies and simplify your pool maintenance with a complete pool chemical brand you can count on — from your first spring dose of Activator to your last winter closing kit.

Frequently Asked Questions

What is DuraChlor and what products do they offer?
DuraChlor is a complete pool chemical brand available at PST Pool Supplies, offering everything you need to keep your pool clean and balanced. Their product lineup includes chlorine tablets and granular sanitizers, multiple shock treatments like Wipe Out and Assault 73, powerful algaecides including Combat 60 and Algae Kil, water balancers for pH and alkalinity, clarifiers like Blue 2000, and specialty products such as stain removers and filter cleaners. DuraChlor also offers convenient seasonal kits so you have exactly what you need for opening and closing your pool.
What is DuraChlor Activator and how does it work?
DuraChlor Activator is a key part of their pool care system, designed to boost the effectiveness of your sanitizer and shock treatments. It works by optimizing your water chemistry so that the chlorine or bromine you add can perform at its best. Think of it as a force multiplier — rather than dumping in extra chemicals, Activator helps you get more out of what you're already using. It's one of DuraChlor's "6 Keys" to pool care, fitting into the Activate step that comes right after cleaning. Pair it with your regular sanitizer for the best results.
What's the difference between DuraChlor's shock treatment options?
DuraChlor offers four distinct shock treatments to fit different needs. Wipe Out is their go-to option and part of the Low Chlorine Program — great for routine weekly shocking with less chemical buildup. Assault 73 is a high-strength calcium hypochlorite shock for heavy-duty situations like algae blooms or cloudy water. Quick Shock dissolves rapidly, making it ideal when you want to swim again soon. Multi Shock Extra does double duty as both a shock and an oxidizer, and it's the recommended choice in DuraChlor's Traditional Care Program alongside chlorine tablets and Blue 2000 clarifier.
Should I use DuraChlor chlorine tablets or granular sanitizer?
Both DuraChlor chlorine tablets and granular sanitizer get the job done, but they serve slightly different purposes. Tablets are the most popular choice for everyday sanitizing because they dissolve slowly in a floater or chlorinator, providing a steady release of chlorine with minimal effort. Granular sanitizer gives you more precise control — you can dial in exactly how much chlorine you add, which is handy for quick adjustments or smaller pools. Most pool owners use tablets as their daily sanitizer and keep granular on hand for spot treatments. DuraChlor also offers Ultra Brom tablets if you prefer a bromine-based system.
What is DuraChlor's recommended pool care routine?
DuraChlor organizes pool care around their "6 Keys" system: Clean, Activate, Balance, Reduce algae, Sanitize, and Shock. They offer two ready-made programs. The Traditional Care Program pairs chlorine tablets with Multi Shock Extra and Blue 2000 clarifier for a straightforward, proven routine. The Low Chlorine Program combines tablets with Wipe Out shock and Nature's Care Pure-Zyme for gentler water that's easier on skin and swimsuits. Whichever program you choose, keep your water balanced at pH 7.2–7.6, alkalinity 80–120 ppm, calcium hardness 200–400 ppm, and stabilizer 30–50 ppm. Add an algaecide weekly for extra protection.
