What's Wrong With Your Pool Water?
Answer 7 quick questions about how your water looks, smells and feels, and we'll point you to the most likely cause -- plus the calculators to fix it.
Green water, cloudy water, a strong chlorine smell that stings your eyes, or spots and rings on the plaster -- pool problems usually fall into one of a handful of buckets, and the fix is different for each one. Guessing wrong wastes chemicals and time, and in some cases makes the problem worse (dumping more chlorine on a chloramine problem, for example, is rarely the right move on its own).
Answer the questions below about how your water looks, smells, and feels, plus anything unusual that's happened recently (weather, bather load, testing), and we'll match you to the most likely root cause with a straightforward plan to fix it.
| Result | Best for |
|---|---|
| Algae Growth | Green or cloudy-green water, low chlorine reading, slippery surfaces -- needs a shock treatment, not just more daily chlorine |
| Cloudy or Hazy Water | Gray or milky haze without a green tint -- usually a filtration or chemical-balance issue rather than algae or chlorine odor |
| Chlorine Smell / Chloramines | Strong chemical smell and eye/skin irritation with normal-to-high chlorine readings -- combined chlorine, not too little sanitizer |
| Staining or Scale Buildup | Rust or dark spots, or crusty white deposits at the waterline -- usually metals or calcium, not a sanitizer or filtration issue |
