The Benefits of a Liquid Chlorine Sanitizer

What is Liquid Chlorine?

One of the most popularly chosen forms for sanitizing pool water is liquid sodium hypochlorite. It is widely used in swimming pools both commercial and residential. In the pool industry this is referred to as liquid chlorine. It is actually a chlorinating compound made of three ingredients, liquid chlorine, water and sodium hydroxide. The correct term is liquid sodium hypochlorite. It is a strong sanitizer and shock. Hasa Sani-Clor is one of the strongest sodium hypochlorite formulas available. The popularity of liquid sodium hypochlorite is primarily due to its availability, cost and efficacy. Also, sodium hypochlorite will not contribute to an increase in calcium or cyanuric acid. It remains one of the purest and simplest formulas for the disinfection of bacteria and the prevention and removal of algae in swimming pools.

Beware of By-Products

While all types of chlorine sanitizers work the same there are by-products left behind that can lead to issues in water maintenance. Calcium hypochlorite (Cal-Hypo) works well as a sanitizer however the by-product left in pool water is calcium. Calcium hardness in the pool is increased which can lead to scale formation on surfaces and heater elements. 1lb. of Cal-Hypo in 10,000 gallons contributes 6 ppm of calcium hardness. Trichlor tablets contain cyanuric acid stabilizer (CYA). Every 3-inch trichlor tablet contains 54% of CYA. High levels of CYA lead to ineffectiveness of free available chlorine in fighting bacteria and preventing algae. The higher the CYA level is the more free available chlorine is needed. Based on current research at 100 ppm of CYA it will take 7.5 ppm of free available chlorine to kill bacteria and prevent algae growth. Every 10 ppm of trichlor in a 10,000-gallon pool contributes 6 ppm of CYA.

Practical Benefits of Liquid for Pool Pros

The only by product left from liquid sodium hypochlorite is sodium chloride better known as salt. Out of all the types of chlorine liquid sodium hypochlorite gives a chlorine generator pool what it needs to function properly. This helps replace salt lost from backwashing or splash out.

Liquid sodium hypochlorite is also the best sanitizer for secondary systems like ozone, UV and AOP. Since liquid does not increase CYA levels or calcium hardness, the cells and units will stay cleaner and scale free longer.

Despite all the information, questions and confusion regarding CYA and the use of Tri-Clor in swimming pools, there is still a reliable, safe and simple way to get chlorine sanitizer. Liquid sodium hypochlorite has been proven through the history of pools to be one of the most cost effective, easy and safest ways to disinfect pool water.
