Dosing notes
Chemical demand changes with temperature, sunlight, bather load, water balance, and existing chemistry.
pH adjustments are approximate by design. Add chemicals in smaller doses, circulate, and retest before final correction.
Always follow your product label and local pool-code guidance.

How this chemical calculator helps
This tool converts pool volume and current readings into practical dosing estimates for common pool treatments including chlorine, pH correction, alkalinity, calcium hardness, stabilizer, and salt.
Important chemistry reality
Pool chemistry is dynamic, not perfectly linear. Temperature, sunlight, cyanuric acid level, bather load, and source water all affect demand. Treat these numbers as calibrated starting points and always retest after circulation.
Safe dosing workflow
Dose in stages, circulate thoroughly, test again, and fine-tune. Avoid combining incompatible chemicals in one addition step, and always follow product-label safety instructions.
