Your Dosing Plan
Your pool is balanced — no chemicals needed today.
Total Alkalinity
BalancedCurrent 100 ppm is in the ideal range (80-120 ppm). No action needed.
pH
BalancedCurrent pH 7.5 is in the ideal range (7.4-7.6). No action needed.
Cyanuric Acid (Stabilizer)
BalancedCurrent 40 ppm is in the ideal range for Arizona (30-50 ppm). No action needed.
Free Chlorine
BalancedCurrent 2 ppm is in the ideal range (1-3 ppm). No action needed.
Calcium Hardness
BalancedCurrent 300 ppm is in the ideal range (200-400 ppm). No action needed.
Order matters: Always adjust alkalinity first, then pH, then CYA, then chlorine, then calcium. Adjusting them out of order causes the next reading to drift.
Wait time: Wait 4-6 hours between doses with the pump running. Retest before adding more chemicals.
Safety: Never mix pool chemicals together. Add each one separately, directly to the pool, with the pump running. Always add acid to water — never water to acid.
Disclaimer: These doses are estimates based on standard formulas. Actual results vary by water chemistry interactions. Always test after dosing.
How to use this calculator
- Test your pool water with a quality test kit (Taylor K-2006 or similar) or test strips. Test kits are more accurate but strips are fine for routine checks.
- Enter your readings above. The calculator instantly shows you the exact dose for each chemical and the order to add them.
- Add chemicals in order: alkalinity → pH → CYA → chlorine → calcium. Wait 4-6 hours between doses with the pump running.
- Retest the next day. Adjust as needed. Most balancing takes 1-3 days to fully stabilize.
