Every Pool Owner Deals With Problems Eventually
No matter how well you maintain your pool, problems happen. Equipment wears out, chemistry gets out of balance, and Florida weather throws curveballs. The key is knowing how to identify the problem quickly and whether it is something you can fix yourself or something that needs a professional.
Here are the most common pool problems Tampa Bay homeowners face and how to troubleshoot each one.
Why This Matters in Tampa Bay
Tampa Bay pools face more stress than pools in most other regions. The combination of heat, humidity, intense UV, heavy rain, and year-round use accelerates wear on equipment and chemicals. Problems that might take weeks to develop in a cooler climate can appear overnight in Florida.
Problem 1: Green Pool Water
What It Means
Green water is an algae bloom. Algae spores are always present in outdoor pools. They explode into visible growth when chlorine drops too low, pH drifts out of range, or your filter is not circulating water properly.
How to Fix It
- Test your water immediately. Check chlorine and pH.
- Brush all pool surfaces to break up algae colonies.
- Shock the pool with 3 to 4 times the normal chlorine dose.
- Run your pump 24 hours until the water clears.
- Clean or backwash your filter once the dead algae clogs it.
- Retest and balance chemistry once the water is clear.
If your pool is dark green or black, the algae bloom is severe and may require professional treatment, multiple shock treatments, and possibly a filter cleaning or replacement.
Problem 2: Cloudy Water
What It Means
Cloudy water is usually caused by poor filtration, high pH, low chlorine, or high calcium hardness. It can also follow a heavy rainstorm that introduces contaminants and dilutes chemicals.

- Check and clean your filter. High filter pressure means it is clogged.
- Test pH and adjust to 7.4 to 7.6.
- Shock the pool if chlorine is below 2 ppm.
- Use a clarifier to help your filter catch fine particles.
- Run the pump for at least 12 hours to circulate and filter.
Problem 3: Pump Not Priming
What It Means
If your pump is running but the basket is not filling with water, the pump has lost its prime. This means air is getting into the suction line somewhere.
How to Fix It
- Check the water level. It must be at least halfway up the skimmer opening.
- Inspect the pump lid O-ring for cracks or dryness. Replace and lubricate if needed.
- Check for air leaks at pipe connections on the suction side.
- Make sure the skimmer and pump baskets are clear of debris.
If the pump still will not prime, the impeller may be clogged or the pump may need professional service. Learn about our pump services.
Problem 4: High Filter Pressure
What It Means
Filter pressure 8 to 10 PSI above the clean starting pressure means your filter is dirty and restricting flow.
How to Fix It
- Sand filter: Backwash until the sight glass runs clear.
- Cartridge filter: Remove and hose off the cartridge elements. Replace if they are older than 1 to 2 years.
- DE filter: Backwash and recharge with fresh DE powder.
If pressure stays high after cleaning, the filter media may need replacement. Schedule a filter service.
Problem 5: Salt Cell Not Producing Chlorine
What It Means
If your salt system shows adequate salt levels but chlorine is low, the salt cell may be scaled, worn out, or not getting enough flow.
How to Fix It
- Inspect the cell for white calcium scale buildup. Clean with a mild acid wash if needed.
- Check salt levels with an independent test. The system display can be inaccurate.
- Verify adequate water flow through the cell. Low flow triggers safety shutoffs.
- Check the cell's age. Most salt cells last 3 to 7 years before needing replacement.

Problem 6: Staining on Pool Surfaces
What It Means
Stains come from metals (iron, copper, manganese) in the water, organic debris (leaves, berries), or chemical imbalances. Tampa Bay well water often contains iron and manganese that cause rust-colored stains.
How to Fix It
- Identify the stain type. Metal stains respond to ascorbic acid (vitamin C). Organic stains respond to chlorine.
- Test your water for metals and address the source.
- Use a metal sequestrant to prevent future staining.
- For severe staining, professional acid washing may be required.
