Estimates, not guarantees

Results are deterministic estimates from your inputs and standard values (8.34 lb/gal, pool geometry, standard dosing increments). Real pools vary — measure your pool and verify a figure before relying on it.

Chemical handling

Water-chemistry dosing results are estimates. Always follow the product label, add one chemical at a time, never mix pool chemicals, add chemical to water (never water to chemical), store chemicals safely out of reach of children, and re-test the water before swimming. Add about ¾ of a dose, re-test, then adjust. This is not a substitute for professional pool service.

No professional advice

Nothing here is professional pool, construction, engineering, health or safety advice. For construction, permitting or persistent water-quality problems, consult a qualified professional.
