Florida is not Arizona. It's not California. It's not Texas. People who move here from anywhere else are surprised — usually by July — that their pool is a much different thing to own here than it was wherever they came from. Orlando is humid. It rains almost every afternoon. Temperatures sit in the nineties for four months. Pollen, oak leaves, and palm debris never quite stop falling. That combination does things to a pool that most of the country never has to deal with.
The people who are happiest with their pools in year three are the ones who understood this in year one.
What Florida actually does to a pool
A Central Florida summer runs warm water temperatures, high humidity, daily rain events, and eight to ten hours of direct UV. Each of those is a separate problem:
- Warm water accelerates chlorine demand. A pool that holds chlorine fine in May can burn through it in 36 hours in July.
- Rain drops pH, dilutes sanitizer, and washes yard debris into the pool from every surrounding surface.
- UV burns off free chlorine. Stabilizer (cyanuric acid) protects it, but too much stabilizer causes its own problems.
- Biological load — algae, pollen, fine organics — is higher here than almost anywhere else in the country.
None of this is a problem if the pool is dialed in. All of it is a problem if it isn't.
Run-time is the first variable
The single most common mistake we see is running the pump too little. Homeowners — usually trying to save money on electricity — cut pump run-time to four or five hours a day in summer. That's when algae takes over.
The right answer isn't to run the pump harder; it's to run it smarter. A variable-speed pump on a longer, slower schedule moves the same water volume as a single-speed pump on a short, fast schedule — at a fraction of the energy cost. Eight to ten hours at low RPM, with a short high-RPM cycle to run the cleaner, is the typical Florida summer schedule.
A variable-speed pump pays for itself within about three summers in Central Florida — and that's before the algae savings.
Chemistry basics, in order
Most pool problems are chemistry problems. Address them in this order:
- pH — test weekly in summer, keep between 7.4 and 7.6.
- Total alkalinity — keeps pH stable; target 80–120 ppm.
- Sanitizer (chlorine or salt system output) — free chlorine 2–4 ppm.
- Stabilizer — 40–70 ppm. Too low and UV eats your chlorine; too high and chlorine stops working.
- Calcium hardness — 200–400 ppm. Low calcium eats plaster.
If any one of these is badly off, nothing else will look right until you fix it. Test in that order; correct in that order.
After every rain
A significant afternoon storm dilutes your pool noticeably. After heavier rains, retest pH and sanitizer the next morning. If the pool is very full, drain a few inches — not because the water hurts anything, but because tile and coping lines read sloppy when water sits above them.
The big three mistakes
- Cutting pump time too aggressively. The goal is energy efficiency, not running the pool less.
- Ignoring the skimmer basket. In Florida, empty it weekly. Every week. Especially after storms.
- Skipping the cartridge or DE clean. Clean filters every three to six months depending on type. A clogged filter is the single most common reason a pool suddenly looks cloudy.
The trade-off no one mentions
A pool in Orlando is more work than a pool in most of the country. That's the honest answer. But it's also used more — for longer seasons, on more days of the year, at more hours of the day — than a pool almost anywhere else. The Florida pool has a longer runway to earn its keep. Taken care of, it does.
