Pool Chlorine

Pool chlorine is a powerful disinfectant and sanitizer designed to keep swimming pools clean, clear, and safe for swimmers. It is a chemical compound, often in the form of granules, tablets, or liquid, that helps eliminate harmful bacteria, algae, and other microorganisms in the water. At Doheny's, you can get high-quality, pro-grade pool chlorine at the lowest prices anywhere. Our pool chlorine is sold in tabs, granular form, or skimmer sticks so you can choose your preferred method of delivery. Shop pool chlorine at Doheny's and make the most of your swimming pool chlorination process, ensuring a safe and clean swimming environment for everyone.

What's the best chlorine for my pool?

You may be wondering; what type of pool chlorine should I use? Choosing the right type of chlorine for your pool depends on your specific maintenance needs, pool type, and water conditions. Doheny's offers plenty of options, ensuring you can find the best chlorine for your pool:

3 Inch chlorinating tablets are large, slow-dissolving, highly concentrated tablets that provide long-lasting chlorination; perfect for consistent chlorination and low-maintenance upkeep. These tablets are typically placed in a floating dispenser, in-line chlorinator, in which they dissolve slowly, releasing chlorine over time. Buy Doheny's chlorine tablets for consistent, healthy pool maintenance.

  • Doheny's Pro-grade 3 Inch Chlorine Tablets are specially formulated with 99% active ingredients and no fillers for 90% available chlorine and 99% Trichloro-S-Triazinetrione. These highly effective chlorine tablets are produced in the USA. Our built-in UV inhibitor helps to protect the chlorine from the sun, maintaining optimal chlorine levels and preventing chlorine burnoff.

Skimmer sticks are long, slow-dissolving chlorine sticks designed to fit directly into the pool's skimmer basket, floating dispenser, or chlorinator. They are great for pools with good circulation systems. However, if using a pool heater, we recommend not putting these sticks into the skimmer basket due to high levels of chlorine output. If you have a pool heater, use a floating dispenser or chlorinator to dispense the skimmer sticks.

  • Doheny's Chlorine Skimmer Sticks Doheny's Chlorine Skimmer Sticks are easy-to-use and slow-dissolving to deliver consistently optimal chlorine levels. With 90% stabilized chlorine, including algaecide and clarifier added, you won't have to worry about bacteria or algae growth in your pool. These 2.5-inch long, 2-inch wide sticks will arrive individually wrapped in a locked, child-resistant bucket for safety.

A great choice for quickly sanitizing your pool, Di-Chlor (Dichloro-S-Triaznetrione) contains cyanuric acid, which acts as a pool stabilizer and is often used for shocking bacteria. If your chlorine level is low and needs immediate attention, fast-dissolving Di-Chlor can be used to quickly raise the chlorine level without raising the pH level in the pool.

  • Doheny's Di-Chlor Granular Chlorine features 56% available chlorine, perfect for destroying bacteria in a hurry. It's calcium-free, so there's no need to worry about clouding. Doheny's Di-Chlor granular chlorine is not meant to be used as a daily chlorinator.

1 Inch chlorinating tablets are the same as our 3 inch tablets, but have a quicker dissolve rate due to their smaller size, producing immediate results. Like our other tablets, they are typically placed in floating chlorine dispensers, in-line chlorinators, and dissolve over time.

  • Doheny's Pro-Grade 1 Inch Chlorine Tablets are made with 99% active ingredients and 90% available chlorine for optimal and efficient sanitization power. They offer the same exceptional quality and value as our 3 inch tablets but dissolve faster for quicker results.

Bromine is a great option for sanitizing pool or spa water because it is gentler on skin, hair, and eyes than traditional chlorine. It is the best choice for spas and hot tubs due to its stability in hot water, lasting longer than chlorine. Bromine dissolves slower than chlorine and works best with non-chlorine oxidizing shock. For the best distribution, let it be dispensed by an automatic feeder or floater.

  • Doheny offers hydria clear 1" bromine tablets that are slow dissolving and highly effective at sanitizing your hot tub or pool. Available in different package sizes like 25 lb and 50 lb, these tablets offer convenience and consistent results. By using hydria clear bromine tablets, you can maintain a clean and comfortable spa environment while minimizing skin and eye irritation.

Frequently Asked Questions about Pool Chlorine

Q. How do Doheny's 3 Inch Chlorine Tablets differ from other brands?

A. Doheny's 3 Inch chlorine tablets are formulated with 99% pure Trichloro-S-Triazinetrione and 90% available stabilized chlorine without any fillers or binders. Their unique manufacturing process results in low-odor tabs that last longer, providing value for money. The built-in UV inhibitor protects the chlorine from sunlight, ensuring optimal chlorine levels even under strong sun rays. Check out our blog on why Doheny's chlorine is the best chlorine to buy for your pool.

Q. How do I use my pool chlorine tablets?

A. Simply add the pool chlorine tablets to a floating chlorinator. Make sure the tablet never directly touches your skin. Wear proper protective gear when handling chemicals, such as gloves and eye protection.

Q. What is the ideal chlorine level for your pool?

A. Doheny's recommends you keep your chlorine level around 1.0-3.0 ppm (parts per million). Keeping chlorine within this range ensures effective sanitation without causing irritation to swimmers and equipment.

Q. What is the difference between chlorine and pool shock?

A. Pool shock is a highly concentrated form of chlorine designed to quickly raise chlorine levels and eliminate contaminants. Regular chlorine maintains daily sanitation, while shock treatments help remove bacteria, algae, and chloramine buildup.

Q. When would I choose brominating tablets vs chlorine tablets?

A. Chlorine tablets are best for outdoor pools, as they are cost-effective, work quickly and can be protected from UV burnoff using cyanuric acid. Choose bromine tablets for hot tubs, spas, or indoor pools because they remain effective in warm water and produce fewer odors. Learn more on our blog about chlorine vs bromine.

Q. Why Choose Bromine Tablets for Hot Tub and Spa Water Sanitization?

A. Bromine tablets, such as Doheny's Hydria clear 1" bromine tablets, offer a gentler alternative to traditional chlorine for sanitizing hot tubs and spa water. Bromine is kinder to skin, hair, and eyes, making it ideal for spa environments. These slow-dissolving tablets effectively sanitize the water, providing a comfortable and safe experience for spa users.
