Pool & Spa Buddy

Test your water, type in the numbers, and Pool & Spa Buddy tells you what is off, what to add, how much, and in what order. READS YOUR TEST Enter pH, free chlorine (or bromine), total alkalinity, calcium hardness, and cyanuric acid from any strip or kit. Each reading is graded against the ideal range on a color scale you can read at a glance. GIVES YOU A TREATMENT PLAN One tap and you get a plain-English plan: which parameter to fix first, what product to use, and the dose for your actual water volume. Alkalinity before pH, pH before chlorine, re-test between steps. KNOWS A SPA IS NOT A SMALL POOL Switch between Pool and Spa. A spa runs hotter, turns its water over faster, is often sanitized with bromine, and a dose that is a rounding error in 15,000 gallons will overshoot badly in 350. The ranges and the math change with the vessel. ANSWERS THE FOLLOW-UP Ask in your own words: why the water is cloudy, what cyanuric acid actually does, how often to test. Plain answers, no chemistry degree needed. FREE, NO ACCOUNT No sign-in, no subscription. We keep the lights on through a short list of test kits and chemicals worth owning, linked to Amazon. PRIVATE BY DESIGN No camera, no location. Your readings and the dosing math never leave your phone; they are not stored or sent anywhere. Only the question you type into Ask goes to our AI service to produce the answer. Pool & Spa Buddy gives general guidance for residential pools and spas. Always follow the directions and safety warnings on the chemical product itself. As an Amazon Associate, Odam Solutions earns from qualifying purchases, at no extra cost to you.
