A Troubleshooting Guide by Aquatec Pool Care
Owning a pool is one of life's greatest pleasures — until something goes wrong. Cloudy water, broken pumps, or strange odors can quickly turn relaxation into frustration. But don't worry: most pool issues are common and can be fixed with the right knowledge.
With over 20 years of experience, Aquatec Pool Care has helped hundreds of homeowners identify and resolve pool problems quickly and professionally. This guide covers the 10 most frequent pool issues and how to handle them — or when to call in the pros.
1. Cloudy Pool Water
What's happening: Cloudy water is often caused by unbalanced chemicals, poor filtration, or debris.
How to fix it:
- Test and balance pH, chlorine, and alkalinity
- Backwash or clean the filter
- Use a clarifier or shock treatment
Aquatec offers in-home water testing and professional chemical balancing to restore crystal-clear water fast.
2. Green Water (Algae Growth)
What's happening: Algae thrive in warm, poorly sanitized pools — turning water green, yellow, or black.
How to fix it:
- Shock the pool with chlorine
- Brush walls and floor thoroughly
- Clean or replace the filter
Aquatec uses advanced algaecide treatments and proven methods to eliminate algae safely and effectively.
3. Weak Water Circulation
What's happening: Poor circulation means chemicals aren't distributed and the pool won't clean properly.
How to fix it:
- Remove debris from skimmer and pump baskets
- Make sure valves are fully open
- Check for air leaks or pump failure
Aquatec technicians are trained to inspect and optimize your system for maximum water flow.
4. Pool Pump Not Working
What's happening: The pump isn't turning on, is making strange noises, or shuts off unexpectedly.
How to fix it:
- Confirm power supply and timer settings
- Check for obstructions in the impeller
- Inspect the motor and capacitor
Aquatec handles full pump diagnostics, repairs, and replacements using high-quality, reliable parts.
5. Stains on Pool Surfaces
What's happening: Stains may be organic (leaves, algae) or metallic (iron, copper).
How to fix it:
- Identify the stain type
- Use targeted stain removers
- Adjust pH and calcium levels to prevent recurrence
Don't risk damaging your pool surface — Aquatec uses safe, specialized methods to treat and prevent stains.
6. Foam on the Water
What's happening: Foam can result from poor-quality chemicals or contamination by soaps, lotions, or hair products.
How to fix it:
- Shock the pool
- Avoid cheap algaecides
- Rinse off before swimming
Aquatec only uses premium, eco-friendly products to maintain clean and balanced water without foam.
7. Strong Chlorine Smell
What's happening: A strong chlorine smell means high chloramines — not high chlorine — and poor sanitation.
How to fix it:
- Shock the pool to break down chloramines
- Improve filtration
- Keep chlorine and pH balanced
Aquatec's water treatment services ensure safe, odor-free swimming conditions.
8. Pool Heater Not Working
What's happening: Water won't heat or the heater fails to ignite.
How to fix it:
- Check thermostat settings and flow rate
- Clean the filter
- Schedule a full heater inspection
Aquatec performs seasonal heater maintenance and repairs to keep your pool warm when you need it.
9. Water Loss or Leaks
What's happening: If water is dropping faster than normal evaporation, you may have a leak.
How to fix it:
- Perform the bucket test
- Check plumbing, skimmer, returns, and light fixtures
- Call a professional for leak detection
Aquatec uses advanced pressure testing and leak detection tools to locate and repair problems quickly.
10. Skimmer Not Pulling Water
What's happening: Water isn't flowing into the skimmer as it should.
How to fix it:
- Check for clogs or air pockets
- Clean the weir flap
- Inspect the suction line for leaks
Aquatec technicians will fully inspect and restore your skimmer's function as part of routine maintenance.

Frequently Asked Questions
How do I know if I have a pool leak?
Perform the bucket test and check plumbing, skimmers, returns, and light fixtures. If water is dropping faster than normal evaporation would explain, call a professional for leak detection.
Why does my pool smell strongly of chlorine?
A strong chlorine smell usually means high chloramines, not high chlorine — a sign of poor sanitation. Shocking the pool to break down chloramines and improving filtration resolves it.
What causes green pool water?
Algae growth, usually from warm, poorly sanitized water. Shocking the pool with chlorine, brushing the walls and floor, and cleaning the filter clears it up.
Why is my pool water still cloudy after I shock it?
Cloudy water is often caused by unbalanced chemicals, poor filtration, or debris. If shocking alone doesn't help, check and clean your filter and retest your water chemistry.
