Common Pool Problems and How to Fix Them

Owning a pool brings fun, fitness, and relaxation—but it also requires attention to maintenance and problem-solving. If you’re dealing with cloudy water, unusual smells, or poor circulation, you’re not alone. Rhode Island pool owners often face the same set of recurring issues, especially during the summer months.

This guide outlines the most common pool problems and how to troubleshoot or fix them quickly before they affect your pool’s safety, water quality, or equipment.

Problem #1: Cloudy Pool Water

Symptoms: Water looks dull, milky, or hazy. Pool bottom is hard to see.

Causes:

  • Imbalanced pH or alkalinity
  • Poor filtration or circulation
  • Dirty filter or clogged skimmer basket
  • High calcium or organic debris levels
  • Aftershock from recent pool treatment

How to Fix It:

  1. Test and balance water chemistry, especially chlorine, pH, and alkalinity
  2. Clean the filter and check pump flow
  3. Shock the pool with chlorine or non-chlorine oxidizer
  4. Use a pool clarifier to coagulate fine particles for easier filtration

Prevention Tip: Run the pump for 8–12 hours daily during swim season and test water weekly.

Problem #2: Algae Growth

Symptoms: Green, yellow, or black patches on pool surfaces; slippery walls; murky water

Causes:

  • Low chlorine levels
  • Poor circulation or neglected cleaning
  • Hot, humid weather or heavy rainfall
  • Unused pool covers trapping debris

How to Fix It:

  1. Brush all surfaces thoroughly to loosen algae
  2. Shock the pool heavily and follow up with an algaecide
  3. Run the pump continuously for 24–48 hours
  4. Clean the filter and vacuum the pool

Prevention Tip: Maintain a free chlorine level between 1.0–3.0 ppm and clean debris promptly.

Problem #3: Pool Water That Smells Like Chlorine

Symptoms: Strong chlorine odor, eye irritation, and swimmers complaining of smell or dryness

Causes:

  • Chloramines (used-up chlorine) building up in the water
  • Insufficient “free” chlorine to break down contaminants

How to Fix It:

  1. Shock the pool to eliminate chloramines
  2. Improve circulation to distribute sanitizer evenly
  3. Test and adjust pH to improve chlorine effectiveness

Prevention Tip: Regularly test free chlorine levels and shock weekly during heavy use periods.

Problem #4: Low or No Water Circulation

Symptoms: Water remains still, cloudy; surface debris not moving toward skimmers

Causes:

  • Clogged skimmer or pump basket
  • Dirty or damaged filter
  • Air leak in the pump or plumbing
  • Malfunctioning motor or impeller

How to Fix It:

  1. Turn off the pump and clean skimmer/pump baskets
  2. Inspect filter pressure and backwash or clean as needed
  3. Check for visible air bubbles in pump basket—may indicate a suction-side leak
  4. Inspect valves and plumbing for cracks or blockages

Prevention Tip: Clean baskets weekly and schedule annual professional inspections for your pump and filter system.

Problem #5: Pool Leaks

Symptoms: Water level dropping faster than normal evaporation rate; soggy grass near pool; air bubbles in return jets

Causes:

  • Cracked skimmer, pipe, liner, or pool shell
  • Loose fittings or connections
  • Leaky pump or valve seals

How to Fix It:

  1. Use the bucket test to confirm if the drop is due to a leak or evaporation
  2. Inspect pool equipment for signs of dripping or moisture
  3. Check liner seams and corners for damage
  4. Call a pool professional to perform a pressure test or dye test for precise detection

Prevention Tip: Keep water chemistry balanced to prevent liner damage and monitor water levels regularly.

Problem #6: Staining or Discolored Pool Surfaces

Symptoms: Brown, green, or blue stains on the pool walls or floor

Causes:

  • Metal deposits (iron, copper) from fill water or equipment
  • Organic debris like leaves or algae
  • Incorrect pH or high mineral content

How to Fix It:

  1. Identify the stain type using a stain test kit
  2. Use metal sequestrant for metal-based stains
  3. Brush and treat organic stains with ascorbic acid or pool shock
  4. Prevent future buildup by using a metal control product and pre-filtering fill water

Prevention Tip: Regularly remove debris and maintain proper chemical balance to avoid surface damage.

When to Call a Professional

Some pool issues can be solved with DIY maintenance, but others require a trained eye. Call a pool technician if:

  • The water remains cloudy after multiple treatments
  • Leaks are visible or suspected underground
  • The pump won’t prime or maintain pressure
  • Algae returns repeatedly despite proper care
  • Electrical components stop working
