How Long Should a Pool Pump Run Each Day in Florida?

Turnover, not hours. The pool needs its entire volume passed through the filter at least once a day, and twice is better in peak summer. A 15,000-gallon pool on a pump moving 40 gallons per minute turns over in about six hours; the same pool on a variable-speed pump running at half speed takes closer to eleven. That is why a neighbor's setting is a bad guide for your pool.

Algae growth tracks water temperature. Above roughly 80°F, which is most of May through October here, algae reproduces fast enough that circulation and sanitizer have to keep up continuously. Below about 65°F it slows to the point where six hours is usually enough. Cutting run time in January saves real money; cutting it in July is how a pool goes green.

During the day, for the most part. Chlorine is consumed by sunlight, so circulating while the sun is up distributes sanitizer when it is being used fastest, and it keeps debris moving toward the skimmer during the hours it actually falls. Splitting the run — a morning block and an afternoon block — works better than one continuous overnight stretch.

Yes, and it usually saves money. A variable-speed pump run longer at a lower speed moves the same water using dramatically less electricity, because power draw falls much faster than flow rate does. The typical Central Florida setup is 10 to 12 hours at low speed rather than 8 at full speed, and the power bill still drops.

Cloudy water first, then algae. Debris settles instead of reaching the skimmer, chemicals stratify rather than mixing, and the filter never sees enough of the water to clean it. Most cloudy-pool calls in summer trace back to either a clogged filter or a run time that was quietly cut to save on electricity.
