Estimates, not professional advice

The calculators give estimates from published guidance and the numbers you enter. Pool and spa chemicals are hazardous: read and follow the label and safety data sheet of every product you use, and never mix chemicals. The results do not replace a professional water test, the advice of your pool builder or service company, local health and building codes, or veterinary and aquarist advice for fish.
