What to Do If Your Pool Is Over-Stabilized

What to Do If Your Pool Is Over-Stabilized

Maintaining a swimming pool is a delicate balancing act. One common issue that many pool owners face is over-stabilization, which occurs when there's too much cyanuric acid (CYA) in the pool water. Cyanuric acid is used to stabilize chlorine, protecting it from being broken down by the sun’s UV rays. However, too much CYA can reduce chlorine's effectiveness, leading to cloudy water, algae growth, and other issues. Here’s what you need to know and do if your pool is over-stabilized.

Understanding Over-Stabilization


Cyanuric acid is beneficial in moderate amounts, typically between 30-50 parts per million (ppm). Levels above this range can cause problems, as chlorine’s ability to sanitize and oxidize contaminants is significantly reduced. This leads to the need for higher chlorine levels to achieve the same sanitizing effect, often resulting in more chemical use and expense.

Symptoms of Over-Stabilization


    Cloudy Water: When chlorine is not working efficiently, contaminants build up, leading to cloudy water.

    Algae Growth: Despite high chlorine levels, algae can start to grow due to the diminished effectiveness of the chlorine.

    Increased Chlorine Demand: You might notice that you’re adding more chlorine than usual without seeing the desired results.

    Chlorine Lock: In severe cases, chlorine can become ineffective, unable to sanitize the pool water adequately.


Steps to Correct Over-Stabilization:


  1. Test your pool

Always start by testing your water using Bliss Pool Test Strips. Check to confirm your Cyanuric Acid/Chlorine Stabilizer level is above 100 ppm. If your pool Cyanuric Acid/Chlorine Stabilizer levels are ideal, your pool is not over stabilized. If your pool Cyanuric Acid/Chlorine Stabilizer levels are not ideal do the following steps.


  1. Turn off equipment if test is not ideal

Switch off the pool filter pump, heater, and any other electrical equipment.

 

  1. Partially drain the pool

You cannot add chemicals to lower the stabilizer level, the pool needs to be diluted with fresh water. Drain about 25-50% of the pool water. then retest and repeat if necessary until CYA levels are within the recommended range.Ensure you follow local regulations and guidelines for disposing of pool water.


  1. Refill the pool

Once you’ve drained your pool, refill the pool with fresh water to the middle of the skimmer line or to the manufacturer's recommended fill level.


  1. Turn on equipment

Switch on the pool filter pump, heater, and any other electrical equipment.


  1. Re-entry 

Test water again using Bliss Pool Test Strips (all 7 parameters) and make any final adjustments using the “Test” section of the app. You can swim in it once all levels are in the ideal range. Re-entry to a treated pool above 4 ppm free chlorine is prohibited due to the risk of severe bodily injury.

  1. Next steps

If after 48 hours your Cyanuric Acid/Chlorine Stabilizer levels have dropped but are not yet within the ideal range, further X draining may be necessary. If Cyanuric Acid/Chlorine Stabilizer levels remain unchanged or have increased, please do not drain any more water, and contact us and we will help you.


  1. Preventing overstabilization in the future

Test and balance your pool 2x weekly using Bliss Pool Test Strips. Ensure that all chemical levels remain within the recommended ranges. Make sure to circulate pool water for at least 8 hours per day & follow the Bliss Pool easycare system (weekly) on the app to help maintain clean and clear water. If the problem persists, or you have any questions, please contact us.


 Conclusion:


Over-stabilization can be a challenging issue, but with the right approach, it’s manageable. Regular testing, proper chemical management, and proactive maintenance are key to keeping your pool water clean, clear, and safe. If you find yourself dealing with high CYA levels, remember that a partial drain and refill, along with a switch to non-stabilized chlorine, are your best strategies for restoring balance to your pool. Enjoy a safe and sparkling pool season!
