Keep your pool balanced
Your Recommendations
⚠️ Important: These are estimates based on standard dosing guidelines, scaled to your pool's volume. Always add chemicals one at a time, with the pump running, then wait and re-test before adding more — especially for pH and alkalinity. Never mix chemicals together. Follow the product label and local safety guidance — if a dose here differs from the label, the label wins. See the Terms of Use & Safety Disclaimer (Settings → About & legal).

Everything the calculator might recommend, plus the test gear and tools to keep your water balanced. Most links open an Amazon search so you can compare brands, sizes and prices; a few go straight to a specific product we use.
⚠️ Note: Most links open a product search — not an endorsement of any specific brand or seller. Always confirm the active-ingredient percentage on the label (it affects dosing), store chemicals separately, and never mix products. Buy only what you need for your pool size. Heads-up: some liquids (chlorine, muriatic acid) ship as hazmat or are store-pickup only, so they may not be available to ship to you.
