Cyanuric acid (stabilizer) calculator
PROCyanuric acid (stabilizer) to reach target CYA.
Short answer: oz ≈ (gal/10k) × (ΔCYA/10) × 13. 20,000 gal, +20 ppm CYA = 52 oz (3.25 lb) stabilizer. Enter your measurements above and the cyanuric acid (stabilizer) calculator returns the quantity, unit conversions and an estimated cost instantly, in imperial or metric — no sign-up needed.

Your Pool's Daily Chlorine Budget: A Pro's Guide to Predicting FC Loss
As a landscape estimator who also manages pool chemistry, I've learned that keeping a pool balanced isn't magic—it's math. This guide shares my field data on predicting daily pool chlorine loss, helping you create a 'chlorine budget' based on sun, swimmers, and your specific poo…
How to Calculate Pool Chlorine Demand: A Pro's Guide to CYA
Ever wonder why your pool eats chlorine, even with a cover? It's not just sun and swimmers. As a pro pool tech, I'll show you how Cyanuric Acid (CYA) is the real key to understanding and calculating your pool's daily chlorine demand. Get this wrong, and you're just wasting money.
How Much Chlorine Per Swimmer? A Pro's Field Data on Bather Load
Ever wonder exactly how much chlorine a swim party consumes? I've tracked the data. On average, a single swimmer consumes about 0.15 ppm of Free Chlorine per hour in a 15,000-gallon pool. Here's a pro's guide to calculating chlorine demand based on bather load, not guesswork.
How a Wrong Pool Volume Estimate Wrecks Your Budget & Water Chemistry
I'm Arend, a landscape estimator. I'll show you how a seemingly small error in your pool volume estimate creates a cascade of expensive problems. We've seen clients waste hundreds on chemicals because they were dosing a 12,000-gallon pool like it was 15,000 gallons. Here's how t…
