NO!Mixing different types of chlorine is a big no-no. Why? Because when you mix them, you're inviting a chemical reaction that could result in dangerous gases or even an explosion. Each type of chlorine has its own unique properties, pH levels, and safety hazards. Mixing them can not only be hazardous but also counterproductive, as they could cancel each other out or create unwanted byproducts.If you're considering switching from one type of chlorine to another, it's crucial to completely empty your feeder or dispensing system and give it a thorough cleaning before adding the new type. Always consult the manufacturer's guidelines or a pool care professional when making such changes.<img src="https://letcheck.b-cdn.net/530/clmg7gz2x0010sh8zc94m3njj.png"><h2 style="text-align: start">The MOST COMMON Chlorine Types</h2><h3 style="text-align: start">Liquid Chlorine (Sodium Hypochlorite, Bleach)</h3><ul><li>Usually Comes As: Liquid</li><li>pH Impact: 13 pH</li><li>Delivery System: Mechanical feeding pump or venturi system</li></ul><h3 style="text-align: start">Cal Hypo (Calcium Hypochlorite)</h3><ul><li>Usually Comes As: Tablet</li><li>pH Impact: 12 pH</li><li>Delivery System: Special feeder to dissolve and dilute the chlorine</li></ul><h3 style="text-align: start">Stabilized Chlorine (Tri-Chlor)</h3><ul><li>Usually Comes As: Solid Tablet</li><li>pH Impact: 2.8-3.0 pH</li><li>Delivery System: Special feeder to dissolve and dilute the chlorine</li></ul>Stabilized chlorine, often known as Tri Chlor, comes with a built-in stabilizer. Now, what does a stabilizer do? It acts like sunscreen for your chlorine, protecting it from the sun's UV rays, which can quickly deplete chlorine levels. However, it's crucial to understand that stabilizer by itself is not a sanitizer, disinfectant, or oxidizer.Too much stabilizer can actually reduce the effectiveness of chlorine, leading to issues like algae growth. So, while stabilized chlorine offers the benefit of longevity in sunlight, the stabilizer component is not a stand-alone solution for pool care.<blockquote>Please note stabilized chlorine can not be used on a spa or splashpad in florida</blockquote><h2>QUICK VIEW COMPARISON TABLE</h2><table><tbody><tr><th colspan="1" rowspan="1" colwidth="166" style="width: 166px;"></th><th colspan="1" rowspan="1">Sodium Hypochlorite</th><th colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Calcium Hypochlorite</th><th colspan="1" rowspan="1">Stabilized Chlorine</th></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Usually Comes As</td><td colspan="1" rowspan="1">Liquid</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Solid Tablet</td><td colspan="1" rowspan="1">Solid Tablet</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Also Known As</td><td colspan="1" rowspan="1">Liquid Chlorine, Bleach</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Cal Hypo</td><td colspan="1" rowspan="1">Tri Chlor</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">pH Impact (pH Level)</td><td colspan="1" rowspan="1">Raises (11-13 pH)</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Raises (10-12 pH)</td><td colspan="1" rowspan="1">Lowers (2-3 pH)</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Chlorine Concentration</td><td colspan="1" rowspan="1">10-12%</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">65-75%</td><td colspan="1" rowspan="1">90%</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Safety Hazards</td><td colspan="1" rowspan="1">Corrosive, fumes can be harmful</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Corrosive, can combust if mixed with organic material</td><td colspan="1" rowspan="1">Harmful if ingested, corrosive</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Delivery System</td><td colspan="1" rowspan="1">Mechanical Pump</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">A special feeder container required</td><td colspan="1" rowspan="1">A special feeder container required</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Pros 1</td><td colspan="1" rowspan="1">Widely Available</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">High chlorine content</td><td colspan="1" rowspan="1">Slow-dissolving</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Pros 2</td><td colspan="1" rowspan="1">Generally cheaper</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Adds calcium to water</td><td colspan="1" rowspan="1">Stabilized</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Pros 3</td><td colspan="1" rowspan="1">Faster to add manually to pools</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Easier to transport than bleach</td><td colspan="1" rowspan="1">Easier to transport than bleach</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Cons 1</td><td colspan="1" rowspan="1">Short shelf life</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Can cause scaling</td><td colspan="1" rowspan="1">Can cause low pH</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Cons 2</td><td colspan="1" rowspan="1">Requires repairs to a mechanical feeding pump or venturi system</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Calcium build-up may need to be removed from filters</td><td colspan="1" rowspan="1">High levels of stabilizer reduce the effectiveness of chlorine &gt;30ppm</td></tr><tr><td colspan="1" rowspan="1" colwidth="166" style="width: 166px;">Cons 3</td><td colspan="1" rowspan="1">Requires more acid to maintain the ideal range of 7.4-7.6 pH</td><td colspan="1" rowspan="1" colwidth="270" style="width: 270px;">Tablet feeder can get clogged and needs cleaning</td><td colspan="1" rowspan="1">Chlorine strength is high but quantity is reduced with the addition of a stabilizer</td></tr></tbody></table><h2 style="text-align: start">What About Salt?</h2>Salt: While salt itself isn't a sanitizer, saltwater generators convert salt into a chlorine compound.

Granular chlorine isn't your everyday chlorine; it's the special ops of pool care. 🕶️💥<h4 style="text-align: start">The Good Stuff:</h4><ul><li>Supplemental Powerhouse: Granular chlorine is like the protein shake of your regular chlorine diet. It boosts your pool's chlorine levels when they're lagging due to an expected high bathing load</li><li>Algae-B-Gone: Got algae? Granular chlorine is your algae assassin. Unlike liquid bleach, which disperses quickly, granules can be placed directly on top of pool floor algae. This increases contact time, making it more effective at eliminating those pesky green invaders.</li></ul><h4 style="text-align: start">The Pro Tips:</h4><ul><li>Dissolve First: Ideally, you should dissolve the granules in water before adding them to the pool. Why? Because the granules themselves may take hours to dissolve. So, mix 'em up in a bucket first for quicker action.</li><li>Know Your Type: Not all granular chlorine is created equal. Some are Tri-Chlor based, and others are Cal Hypo based. The difference? Tri-Chlor lowers your pool's pH, while Cal Hypo raises it. Choose wisely!</li><li>Shock and Awe: Granular chlorine is the go-to for "shocking" your pool. It breaks up chloramines—the stuff that makes your pool smell like, well, a pool. Shocking restores your water to its crystal-clear glory.</li></ul><h4 style="text-align: start">The Fine Print:</h4><ul><li>Read the Label: Seriously, do it. Some granular chlorines have added stabilizers or other chemicals. Know what you're putting in your pool.</li><li>Don't Mix Types: This is a biggie. Mixing different types of granular chlorine can lead to explosions or flammability issues. Yeah, you read that right—explosions. So, keep 'em separated!</li></ul>So, the next time your pool needs a pick-me-up, consider granular chlorine. But remember, it's like the espresso shot of pool care—handle with care.<img src="https://letcheck.b-cdn.net/530/clmg6hnts00l4o59nelk762l8.png"><h2>Suggested Best Use-Cases by Type of Commercial Aquatic Facilities</h2><h4 style="text-align: start">Sodium Hypochlorite (Liquid Chlorine, Bleach)</h4><ul><li>Large Public Pools: Due to its fast absorption rate, it's ideal for large pools that need quick chlorination.</li><li>Water Parks: Great for slides and lazy rivers where water flow is fast and needs quick treatment.</li><li>Spas and Hot Tubs: Effective for high-temperature environments.</li></ul><h4 style="text-align: start">Calcium Hypochlorite (Cal Hypo)</h4><ul><li>Hotel Pools: Moderate absorption rate and added calcium make it suitable for smaller, less busy pools.</li><li>Gym Pools: Ideal for indoor pools where quick chlorination isn't as critical.</li><li>Older Pools: Adds calcium, which can be beneficial for older pools with plaster surfaces.</li></ul><h4 style="text-align: start">Stabilized Chlorine (Tri Chlor)</h4><ul><li>HOA/Residential Complex Pools: Slow-dissolving nature makes it ideal for pools that don't have high bather loads.</li><li>Saltwater Pools: Works well as a secondary sanitizer and stabilizer.</li></ul><h2>ACTION STEPS</h2><ul data-type="taskList"><li data-checked="false" data-type="taskItem"><label><input type="checkbox"></label><div>Identify Your Current Chlorine Type: Check what you're currently using.
