Liquid chlorine is manufactured by bubbling chlorine gas through a solution of caustic soda. The resulting yellow liquid yields 15% available chlorine, but the concentration is very unstable and within two weeks, the available-chlorine level will drop to approximately 12.5 percent and after 30 days it can drop to as low as 9%. Sunlight and high temperatures can increase the rate of degradation.
Besides the low concentration of available chlorine, sodium hypochlorite also greatly increases total dissolved solids and has an extremely high pH of 13. Neutralizing the pH requires approximately 1 part muriatic acid per 8 parts liquid chlorine.
As you can see in the first place you are paying for very little real chlorine, secondly if you aren't adding the acid that it calls for you are going to do serious damage to your pump and filter due to the total dissolved solids and high ph in liquid chlorine.
Trichlor is designed for the cooler water of swimming pools and contains the highest percentage (90%) of available chlorine of all the different chlorine compounds. Trichlor should never be used in a spa as the high temperatures will cause it to dissolve very quickly. Available as a l-inch tablet, 3-inch tablet, a stick or a cartridge, it has a long shelf life, and it is very slow dissolving in cool water. This allows it to work extremely well in swimming pool floaters and erosion-type feeders.
Trichlor has a very low pH of 2.9 and requires frequent monitoring and adjustment of pH to prevent damage to equipment and other metal parts. Neutralizing the pH requires approximately 1 part soda ash per 4 parts trichlor.
Trichlor is produced by drying and cooling the sodium salt of cyanuric acid in the presence of chlorine gas. The resulting compound provides 90% available chlorine.
As you can see the best route to go is Trichlor or as it is sometimes referred to as "stabilized chlorine".
We are proud to sell both the new silk sticks from BIOGUARD which gives you the same soft feeling as the new salt pools as well as other quality stabilized chlorine products. For the reasons listed and because we care about you as a customer and realize that you have a lot invested in your pool we do not sell liquid chlorine. We of course want you to purchase from us but no matter where you do purchase your pool products please stay with a quality stabilized chlorine and steer clear of liquid.
