The Truth About Green Pools: Causes & Fixes

Few things are more frustrating than walking outside to find your pool water has turned green. It’s not just unappealing. It’s unsafe to swim in. As a leading Naples pool service company, we often get calls about green pools, especially after heavy rains, seasonal changes, or equipment problems.

Here’s what you need to know about what causes green pools and how to fix them:

Why Pools Turn Green

• Algae Growth: Warm Florida weather plus unbalanced chemicals is the perfect recipe for algae.

• Low Chlorine Levels: Without enough chlorine, algae can grow overnight.

• Poor Circulation: If your pump or filter isn’t working properly, your pool water can’t stay clean.

• Heavy Rainstorms: Stormwater adds phosphates and contaminants that fuel algae blooms.

Why DIY Fixes Don’t Always Work

Many homeowners try to shock the pool themselves, but without the right balance of chemicals and proper filtration, the green water often comes back. Worse, adding too much chlorine without addressing the root cause can damage pool surfaces and equipment.
