Uh oh. You walk outside, and your pool looks more like a pond. Green water is one of the most common (and frustrating) issues pool owners face across Florida—especially in places like Clermont, Winter Garden, and Reunion where warm weather and daily use can speed up algae growth.
In this guide, we’ll break down why your pool water turns green, what it actually means, and how to fix it—before it costs you more than a new swimsuit.
What Causes Green Pool Water?
It usually boils down to two culprits:
Algae Bloom: The #1 reason for green water. This happens when chlorine levels drop too low or the water circulation isn’t doing its job.
Metals in the Water: If the water contains copper or iron, it can oxidize and turn green—especially after shocking the pool.
Other possible causes:
Poor pool pump or filter performance
Broken or clogged return jets
Faulty pool automation systems (especially common in smart homes)
How to Fix Green Pool Water
Test the Water: Use a test kit to check chlorine, pH, and alkalinity. If you’re unsure, schedule a free pool repair inspection and we’ll come out with professional tools.
Shock the Pool:Â Add chlorine shock treatment to kill algae or bacteria.
Scrub & Circulate: Brush the pool walls and floors thoroughly. Run your pump non-stop for 24–48 hours.
Clean the Filter:Â A dirty filter will trap dead algae and reduce circulation. Backwash or replace as needed.
Retest:Â Once the water clears, re-balance the pool chemistry.
When It's Not Just Algae
Sometimes, green water is a sign of deeper issues. We’ve seen this firsthand in Clermont, where:
Faulty automation systems weren’t triggering the chlorinator
Cracked pipes caused stagnation in return lines
Pool pumps needed full replacement, not just cleaning
If you’ve tried all the DIY fixes and your pool is still green—it’s time for a pro.

If your water is staying green despite shocking, brushing, and filter cleaning, there may be a deeper issue:
A failing pump or clogged return line
