There’s nothing quite as inviting as a crystal-clear swimming pool on a scorching day. But what happens when that clear blue oasis turns into a cloudy lagoon overnight? It’s a common problem, but not one without solutions. Let’s dive into the top nine causes of cloudy swimming pool water and how to bring back that sparkling clarity.

 

1. Imbalanced Pool Chemicals

 

Swimming pool chemistry can be a delicate balancing act. Imbalances can quickly turn a clear pool into a murky mess. This can happen due to:

 

  • High pH and alkalinity levels
  • Low chlorine or other sanitiser levels
  • High calcium hardness

 

Fix: Regularly test and adjust your pool water’s chemical levels.

 

2. High TDS Levels

 

Total Dissolved Solids (TDS) are tiny particles that can cloud your pool water. This can occur when:

 

  • Pool chemicals dissolve and leave residue
  • Dirt, leaves or other debris enter the pool

 

Fix: Regular backwashing and filter cleaning can help manage TDS levels. If it persists, a partial water replacement may be necessary.

 

3. Insufficient Filtration

 

Your pool’s filtration system is key to maintaining clear water. If it’s not working effectively, it can lead to cloudiness. This can happen when:

 

  • The filter is too small for the pool size
  • The filter isn’t running long enough each day
  • The filter is clogged or needs replacing

 

Fix: Ensure your filter size is adequate, run it for at least 8 hours daily and clean or replace it as needed.

 

4. Inadequate Circulation

 

Poor water circulation can lead to pockets of cloudy water. This could be due to:

 

  • A failing pool pump
  • Blocked skimmer boxes or return jets

 

Fix: Regular pool maintenance should include checking the pump, skimmer boxes and return jets for any blockages or malfunction.

 

5. Algae Blooms

 

Algae love warm, sunny weather and can bloom rapidly, causing cloudiness. Algae blooms can occur if:

 

  • Chlorine levels are too low
  • The pool isn’t regularly brushed or vacuumed

 

Fix: Regularly brush and vacuum your pool and maintain optimal chlorine levels to prevent algae growth.

 

6. Pollutants

 

Everyday substances can cloud your pool water. This includes:

 

  • Oils and lotions from swimmers
  • Pet hair or dander

 

Fix: Regularly skim and vacuum your pool and encourage swimmers to rinse off before entering.

 

7. High Calcium Hardness

 

Hard water can cause cloudiness, especially in heated pools. This can happen if:

 

  • Your local water supply has high calcium levels
  • Calcium-based pool chemicals are overused

 

Fix: Use a calcium sequestrant or switch to non-calcium based pool chemicals.

 

8. Overuse Of Pool Chemicals

 

  More is not always better when it comes to pool chemicals. Overuse can lead to cloudiness.
Fix: Follow the recommended dosages and adjust as necessary based on
regular water testing .

 

9. Environmental Factors

 

Sometimes, Mother Nature is to blame. Cloudiness can result from:

 

  • Pollen or dust storms
  • Heavy rain which washes debris into the pool

 

Fix: Regularly skim and vacuum your pool and consider a pool cover for severe weather events.
