9 Causes Of Cloudy Pool Water And How To Fix It
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.
