5 of 5 calculators are live. Everything else below is on the roadmap — check back as more launch.
Calculate pool volume, chemical dosage, heater sizing, and water-feature capacity. Accurate volume measurements are the foundation of safe water chemistry and properly sized equipment — these tools make sure you get both right.
Quick Tips
- Test pool water at least twice a week during swim season; pH should stay between 7.2 and 7.6 for safe, comfortable swimming.
- Size your pool heater based on surface area, desired temperature rise, and average wind exposure — not just gallons.
- Run your pump long enough to turn over the entire pool volume at least once every 8–12 hours for proper filtration.
