About
Pool Chem ends the guesswork. Enter your pool or spa volume once, then log your water test — free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, and salt. In seconds, Pool Chem tells you the exact amount of each chemical to add and the order to add them safely. No more chemistry. No more "add a little and hope." Just clear water. • Snap a photo of your test strip or digital tester — readings fill in automatically • Exact doses in ounces, grams, or cups — sized to YOUR products' strengths • Plain-English reasons for every adjustment, with the math you can check • Safe ordering: alkalinity before pH, chlorine added last, never mixed • Shock & algae (SLAM) helper for green-pool recovery • Salt-pool (SWG) mode, multi-pool & spa profiles • Maintenance reminders, season trends, PDF export, and widgets Free: one pool with full manual dosing. Pro unlocks photo scan, unlimited pools, trends, shock helper, and export. Informational tool only — always follow your chemical manufacturer's label directions and never mix pool chemicals.
