What is a Pool Stabilizer (CYA)?

A pool stabilizer, scientifically known as Cyanuric Acid (CYA), is a chemical compound that protects chlorine from being destroyed by the sun’s ultraviolet (UV) rays. Without a stabilizer, the chlorine in your pool can evaporate rapidly — sometimes losing up to 90% of its effectiveness in just a few hours of sunlight.

By maintaining the correct CYA level, you help your chlorine last longer, allowing it to disinfect efficiently and keep your pool water safe and clear. However, too much stabilizer can reduce chlorine’s effectiveness, leading to cloudy water and possible algae growth. That’s why accurate dosing is so important — and that’s exactly where the Pool Stabilizer Calculator comes in.

Why You Need a Pool Stabilizer Calculator

Balancing pool chemistry isn’t just about adding chemicals; it’s about adding the right amount. The Pool Stabilizer Calculator takes key factors such as:

• Pool volume (in gallons)
• Current CYA level (ppm)
• Target CYA level (ppm)
• Type of stabilizer used (granular or liquid)

It then calculates the exact dose you need to achieve the perfect balance — without wasting chemicals or overcorrecting.

This tool ensures that your chlorine remains effective and your pool remains crystal-clear. Whether you’re managing a small backyard pool or a large resort pool, the calculator adapts to your needs and provides instant, easy-to-understand results.

How the Pool Stabilizer Calculator Works

The calculator uses a simple formula based on standard dosing principles:

1. You enter your pool’s volume in gallons.
2. Input your current CYA level (how much stabilizer is already in your pool).
3. Enter your target CYA level, which typically falls between 30–50 ppm for most outdoor pools.
4. Choose your stabilizer type — granular (100% CYA) or liquid (25% CYA solution).

Once you click “Calculate Dose,” the tool instantly displays:

• The CYA increase required (in ppm).
• The exact amount of stabilizer to add (in ounces or fluid ounces).

If you’ve already reached your target CYA level, the calculator will notify you — saving you from unnecessary chemical use.

Understanding the Results

Your results will include two key metrics:

CYA Increase Required (ppm):
This shows how much your stabilizer level needs to rise to reach the target range.

Required Chemical Dose:
This tells you precisely how much granular or liquid stabilizer to add. For instance, a granular stabilizer typically requires about 1.35 ounces per 10,000 gallons to raise CYA by 1 ppm, while liquid stabilizer needs around 5.5 fluid ounces for the same effect.

Pro Tips for Using Pool Stabilizer Effectively

• Dissolve granular stabilizer before adding it to your pool. This prevents undissolved residue from sitting on the pool floor.
• Allow 24 hours after dosing before re-testing CYA levels, as full stabilization takes time.
• Avoid over-stabilization — too much CYA can “lock” chlorine, reducing its disinfecting power.
• Regularly test your pool water to ensure balance among CYA, chlorine, and pH levels.

Ideal CYA Levels

For most pools, recommended stabilizer levels are:

• 30–50 ppm for outdoor pools with direct sunlight
• 20–30 ppm for shaded or indoor pools
• 60–80 ppm for saltwater pools

Maintaining the correct range ensures maximum chlorine efficiency while preventing overuse of chemicals.
