Pool stabilizers are essential pool chemicals for pool maintenance. Their function is to maintain the level of free chlorine in the pool. They play an important role in maintaining the long-term disinfection of pool chlorine disinfectants.
How the pool stabilizer work
The pool stabilizers, usually refers to cyanuric acid, is one chemical that can allow the chlorine in the pool to be stably present under sunlight.. Cyanuric acid forms a stable chlorine complex by freely combining with hypochlorous acid, thereby slowing down the decomposition in ultraviolet light. Without chlorine stabilizers, ultraviolet light can cause the chlorine in the pool to decompose rapidly in less than two hours. This will not only increase the loss of chlorine and increase costs, but may also cause algae and bacteria to grow rapidly in the pool.
The role of pool stabilizers
UV protection: Stabilizers absorb ultraviolet light and reduce the rate at which chlorine molecules decompose due to light.
Keep chlorine active: Chlorine combined with cyanuric acid still effectively kills harmful microorganisms such as bacteria and algae.
This protection mechanism is absolutely necessary for outdoor pools because they are exposed to sunlight for a long time, and unstabilized chlorine will quickly lose its effectiveness.
Common forms of swimming pool stabilizers
Common forms of swimming pool stabilizers include the following:
Cyanuric acid powder or granules
Appearance: white powder or granular solid.
Use: directly added to swimming pool water, slowly dissolved to stabilize the residual chlorine in the pool water.
Cyanuric acid tablets
Appearance: pressed into regular tablets.
Features: easy to operate, able to control the dosage more accurately.
Use: usually used in small or family swimming pools, placed in a floating dispenser for slow release.
Compound chlorine products with stabilizing effect
Sodium dichloroisocyanurate granules and trichloroisocyanuric acid tablets
Features:
Sodium dichloroisocyanurate (SDIC): contains 55%-60% available chlorine. Can be used for disinfection or shock.
Trichloroisocyanuric acid (TCCA): contains 90% available chlorine, suitable for continuous replenishment of chlorine and cyanuric acid.
Use: while replenishing the effective chlorine required for disinfection, stabilize the residual chlorine concentration and reduce water quality fluctuations.
Precautions for using swimming pool stabilizers
1. Over-stabilization
When the cyanuric acid level is too high, it will reduce the activity of chlorine, thereby reducing the disinfection ability of the pool water. Therefore, it is necessary to pay attention to the dosage and test it regularly.
2. Not suitable for indoor swimming pools
Indoor swimming pools are not exposed to direct sunlight, so stabilizers are usually not required. If misused, it may cause unnecessary chemical balance problems.
3. Difficulty of testing
Detection of cyanuric acid concentration requires special testing equipment. Ordinary chlorine tests cannot detect the stabilizer content, so appropriate testing tools must be purchased regularly.
How to use swimming pool stabilizers correctly
1. Check the stabilizer concentration
The ideal concentration of cyanuric acid in swimming pool water is 30-50 ppm (parts per million). Below this range will result in insufficient protection, while above 80-100 ppm may result in over-stabilization (the so-called “chlorine lock”), affecting the bactericidal effect of chlorine. Which may cause the water to become cloudy or algae to grow. At this time, it is necessary to partially drain and refill with clean water to reduce the concentration.
2. Correct addition method
Granular stabilizers should be dissolved in water before addition, or added gradually through a filter system to avoid direct sprinkling into the swimming pool to cause particle deposition, which may damage the swimming pool surface.
3. Regular monitoring
Monitor cyanuric acid levels weekly using pool test strips or professional test tools to ensure they are always within the recommended range and adjust as needed.
Some pool maintainers prefer chlorine products with their own stabilizers, such as TCCA and NaDCC. These products combine chlorine and cyanuric acid to provide a one-stop solution.
Advantages:
Easy to use and suitable for daily maintenance.
Chlorine and stabilizer can be replenished at the same time, saving time.
Disadvantages:
Long-term use may lead to excessive accumulation of cyanuric acid.
Regular testing and timely adjustment are required.
In the use of pool chlorine stabilizers, correct use and regular monitoring are essential. Please strictly follow the product manual for use. Please take personal protection when applying. If you have any questions, please consult your pool maintenance expert.
