Liquid Pool Stabilizer (CYA) Calculator

Find out exactly how much liquid Cyanuric Acid to add. Liquid stabilizer works instantly compared to granular CYA, but dosing calculations are entirely different.

Quick Conclusion
1 gallon of liquid stabilizer will raise the Cyanuric Acid (CYA) level of a 10,000-gallon pool by exactly 32 ppm. It is more expensive but dissolves instantly.

Liquid stabilizer is the preferred choice for vinyl liner pools and fiberglass pools because granular CYA can take days to dissolve and may burn the surface if it sits on the floor.

Actionable Steps

1. Shake the liquid stabilizer jug vigorously (it settles heavily). 2. Use the calculator to find the exact ounce requirement. 3. Pour directly into the skimmer slowly with the pump running. 4. Rinse the jug with pool water to get all the thick slurry out.

Pro-Tip

If the liquid seems stuck at the bottom of the jug, dip the jug in the warm pool water for 10 minutes, then shake it violently. It's a thick suspension, not a true liquid.

Frequently Asked Questions

Do I need to wait 7 days to test like with granular CYA?

No. Liquid stabilizer is a slurry of sodium cyanurate that is instantly active. You can test your water again within 3 hours.

Does liquid stabilizer lower pH?

Unlike granular Cyanuric Acid (which is highly acidic), liquid stabilizer is pH balanced and will not significantly drop your pool's pH or alkalinity.
