Overstabilization
 

What is overstabilization?
The build-up of cyanuric acid in swimming pool water, which usually results from the extended use of stabilized sanitizers in conjunction with stabilized shock products.

Overstazbalization will significantly decrease the effectiveness of chlorine in killing germs, bacteria and algae.  Small levels of cyanuric acid do serve a purpose in protecting chlorine from sunlight degradation.  However, too much will negate any benefit and cause problems.  The recommended levels of Stabilizer (cyanuric acid) are between 40 and 60 ppm.

Calcium Hypochlorite based shock products such as Pool Breeze® Shock Treatment and Superchlorinator or Pool Breeze® Granular Chlorinator and Shock Treatment will not increase the stabilizer level in your pool.POOLIFE® calcium hypochlorite sanitizers and shock products offer the complete solution to overstabilization.  Several state health departments have eliminated or banned the use of cyanuric acid based product in public swimming pools.  Ensure you practice responsible pool care and have a reliable and balanced pool care program. 

What are the symptoms of overstabilization?
•  Cloudy water 
•  Visible algae, despite high chlorine readings 
•  Adding chlorine to the pool water does not get rid of the algae 


What solutions are there to overstabilization?

1. Turn on the pool pump, ensure the filter does not need to be backwashed or cleaned and make sure 
     it is running properly. 
2. Test and adjust the stabilizer levels to 20 - 50 ppm by partially draining some water from the pool and
     then top-off with fresh water.
3. Adjust the TA to 60 - 120 ppm (depending on your primary sanitizer), the pH to 7.2 - 7.6 and the
     chlorine to 1 - 4 ppm. 
4. Continue with your routine pool maintenance program. 
5. Always use a calcium hypochlorite base shock product (read the active ingredient on the label).
