Foamy pool water may look like something out of a spa commercial, but for homeowners in North Port, Port Charlotte, Punta Gorda, Rotonda, and across Charlotte County, it’s usually a sign that something is wrong. If your pool looks more like a bubble bath than a place to swim, don’t panic—this guide will help you figure out why it’s happening and what to do about it.

Why Does Pool Water Foam?

Pool foam is caused by surfactants—substances that reduce surface tension and create bubbles. Surfactants can sneak into your pool in several ways:

  • Residue from soaps, shampoos, and laundry detergents
  • Excessive pool chemicals or algaecides
  • Decomposing organic matter (leaves, pollen, or dead algae)
  • High swimmer load during busy weekends or snowbird season
  • Cosmetics, lotions, and sunscreen washing off into the water

In Charlotte County, where summer storms bring pollen and debris, foam is even more common if the pool isn’t serviced regularly.

Step 1: Test Your Water Chemistry

The first thing to do when foam appears is to check your pool’s chemical balance. Grab a testing kit or strips and look for:

  • Chlorine levels → Low chlorine lets organic matter build up.
  • pH balance → Out-of-range pH can increase foam.
  • Total dissolved solids (TDS) → High TDS levels make water cloudy and foamy.

If you’re in Port Charlotte or Punta Gorda, you know heavy rains can dilute chemicals quickly, so testing is especially important after a storm.

Step 2: Shock the Pool

If the chemistry looks off, the fastest solution is a shock treatment:

  1. Add chlorine shock according to pool size.
  2. Run the pump continuously for 24 hours.
  3. Brush and vacuum to remove any residue.

💡 Local pros at Florida Detail often recommend shocking after big pool parties or seasonal transitions, especially for snowbird homeowners returning to North Port or Rotonda.

Step 3: Rule Out Algaecide Overuse

Believe it or not, one of the most common culprits for foamy pools in Charlotte County is too much algaecide. Certain low-cost algaecides contain copper or surfactants that create bubbles.

  • If you’ve recently added algaecide, check the dosage.
  • Avoid bargain-brand products with high surfactant levels.
  • Stick with polyquat 60, which is less likely to foam.

Step 4: Eliminate Organic Debris

Florida pools are surrounded by oak leaves, palm fronds, and constant pollen. All of these contribute to foamy water. To prevent buildup:

  • Skim the pool daily.
  • Use a leaf net after storms.
  • Clean filters regularly.

In Rotonda, where many pools are screened but still gather fine debris, filter maintenance is critical.

Step 5: Call in a Professional

If the foam keeps coming back, it may be time to call a local expert. A pool technician can:

  • Perform advanced water testing
  • Inspect pump and filter systems
  • Identify hidden chemical imbalances
  • Recommend long-term maintenance strategies
