Most pool owners should test at least twice a week during swimming season, and more often after heavy rain, high bather load, or when opening the pool for the season.
Cloudy water often signals a filtration or chemical imbalance issue, while green water almost always means algae growth from insufficient sanitizer levels. Run our calculator above with your test results for exact correction amounts.
Basic weekly maintenance — testing, adding chemicals, and skimming — is very doable for most pool owners with the right tools; equipment repairs and major chemical imbalances are where hiring a professional often makes more sense.
Adding chemicals without an accurate current test reading is the most common mistake — this can lead to over-correction that creates a new imbalance. Always test first, then dose based on the actual results.
