What Causes Cloudy Pool Water (and How to Fix It)
There’s nothing more frustrating than waking up to a cloudy pool—especially in Florida, where you count on your backyard oasis to beat the heat. At Orchid Pools, we regularly help homeowners clear up murky water and keep their pools sparkling clean. If you’re wondering why is my pool cloudy, this blog will walk you through the most common causes and how to fix them fast.
Top 5 Reasons Your Pool Water Is Cloudy
1. Poor Filtration or Circulation
Your pool’s filter system is the first line of defense against cloudy water. If it’s clogged, running on a short cycle, or not working at all, debris and microscopic particles can build up quickly.
Fix:
Check and clean your pool filter (cartridge, sand, or DE).
Make sure your pump is running at least 8–12 hours a day during peak season.
Clean your skimmer and pump baskets weekly.
2. Unbalanced Water Chemistry
Improper chlorine levels, pH, and alkalinity are a major cause of cloudy pool water. High pH or low chlorine, especially, can allow bacteria and algae to grow.
Fix:
Test your pool water using a reliable test kit.
Adjust pH (ideal range: 7.2–7.6), alkalinity (80–120 ppm), and chlorine (1–3 ppm).
Shock your pool if chlorine is too low.
3. Too Many Particulates (Pollen, Dirt, Debris)
Florida pools—especially those surrounded by trees or located near construction—tend to collect more debris, which can cause cloudiness if not cleaned regularly.
Fix:
Use a pool vacuum to clean the floor and walls.
Skim surface debris daily.
Add a clarifier to help the filter trap fine particles.
4. Algae Bloom Beginning to Form
Cloudy water can be a warning sign of early-stage algae growth. Left untreated, it can turn green quickly.
Fix:
Brush all pool surfaces thoroughly.
Shock the pool and follow up with algaecide if needed.
Run your filter continuously for 24–48 hours.
5. High Calcium Hardness or TDS (Total Dissolved Solids)
Hard water and dissolved minerals can create a hazy appearance in your pool.
Fix:
Test for calcium hardness (ideal: 200–400 ppm).
Partially drain and refill your pool if TDS or calcium is too high.
Use a sequestering agent if needed.
