Living in Pinellas County means year-round access to sunny days and poolside relaxation. But with our high humidity, intense UV rays, salty air, and frequent rain showers, keeping your pool water crystal clear takes more than a splash of chlorine.
At Legion Pools, we understand how Florida’s coastal climate impacts pool chemistry. Here’s your go-to guide on how to balance pool chemicals properly in this humid environment—so your pool stays clean, safe, and swim-ready all year long.
1. Keep Chlorine Levels Consistent
☀️ The Challenge:
High humidity and direct sun exposure in Pinellas rapidly burn off free chlorine—especially in uncovered pools.
✅ The Fix:
- Keep free chlorine between 2–4 ppm (parts per million)
- Use stabilized chlorine or add cyanuric acid (CYA) to protect chlorine from UV degradation
- Consider a saltwater system to generate chlorine continuously and reduce manual dosing
Tip: Always test chlorine levels after heavy rains or extra swimmers.
2. Balance pH Weekly
🌧️ The Challenge:
Frequent rain lowers pH, while body oils and chemicals raise it. An unbalanced pH can lead to cloudy water, scaling, and eye irritation.
✅ The Fix:
- Ideal pH level: 7.4–7.6
- Use pH increaser (soda ash) or pH reducer (muriatic acid) as needed
- Test your pH at least 1–2 times per week
3. Watch Alkalinity—Your Pool’s pH Buffer
🔁 The Challenge:
Fluctuating weather and chemical use can throw total alkalinity out of balance, affecting your pH stability.
✅ The Fix:
- Maintain alkalinity between 80–120 ppm
- Add baking soda to raise it, or muriatic acid to lower it
- Adjust alkalinity before pH for more effective results
4. Monitor Calcium Hardness
🌊 The Challenge:
Pinellas County’s water is typically soft, but heat and evaporation can cause calcium levels to rise over time, leading to scale buildup on tiles and equipment.
✅ The Fix:
- Ideal calcium hardness: 200–400 ppm
- Add calcium chloride to increase, or dilute with fresh water to decrease
- Watch for white flakes or rough surfaces—signs of excess hardness
5. Check Stabilizer (CYA) and Phosphates
🔅 The Challenge:
Too much cyanuric acid (CYA) reduces chlorine’s effectiveness; too little and UV rays burn it off. Humid environments also promote algae growth fed by phosphates.
✅ The Fix:
- Maintain CYA at 30–50 ppm
- Use phosphate removers to prevent algae
- If CYA is too high, partially drain and refill with fresh water
6. Shock Weekly in Humid Months
🌡️ The Challenge:
Humidity, high bather loads, and debris raise demand on sanitizers—especially in summer.
✅ The Fix:
- Shock your pool once a week with a chlorine or non-chlorine oxidizer
- Always shock after storms, parties, or visible algae growth
7. Test Often, Adjust Quickly
In Florida’s humid climate, chemical levels change fast. Use a digital test kit or bring a sample to Legion Pools for professional testing.
We recommend:
- Testing chlorine and pH 2–3 times per week
- Full chemical tests weekly
- Adjusting quickly to prevent problems before they start
