Stabilizer, also known as cyanuric acid or conditioner, is vital to your pool's chemical health. But, there is such a thing as over and under stabilization. How do you know if your stabilizer is working to benefit your pool?


Your stabilizer level should be between 20 and 80 parts per million (ppm). If the stabilizer is in range, your chemicals have the opportunity to work for your pool's benefit. Stabilizer slows chlorine burn-off, thereby extending the life of your chlorine. Problems arise when your stabilizer is too low or too high.

Too High

- High stabilizer will etch plaster pool surfaces, making them porous and abrasive over time.

- Chlorine no longer kills dangerous microorganisms in your water as well, so you will be using more chlorine than normal.

- If your stabilizer gets extremely high, it can turn your pool water purple, which is definitely not as cool as it sounds.

Too Low

-If your stabilizer is too low, you will not be able to hold a solid chlorine level in your pool to water.

- Without stabilizer, your pH level will go from 7.8 to 8.5 --> normal range is 7.4-7.6.

How can you fix the problem?

There is an alternative solution to stabilizer if you just can't seem to get the levels correct in your pool water's chemistry. It's called Dr. Dryden's Enhance. This chemical replaces stabilizer. Depending on your pool's volume, you will use 1/2-1 gallon of enhance per month during pool season. This way, you don't have to stress about over or under-stabilization. You can pick this up at Angie's any time!
