Guide on how to deal with cloud pool & hot tub water
How to clear cloudy pool water
Follow these steps in order to identify the cause, restore water balance and help your filtration system remove the cloudiness.
-
Test the water
Check the free chlorine and pH levels before adding any treatment.
-
CHECK THE FILTRATION
Empty the pump and skimmer baskets. Clean or backwash the filter and check that the water is circulating correctly.
-
ADJUST THE PH
Bring the pH into the recommended range shown on your testing kit and product label. Balanced pH helps chlorine work effectively.
-
BRUSH AND VACUUM
Brush the pool walls, steps and floor to loosen dirt, fine debris and any early algae growth. Vacuum away settled material.
-
APPLY SHOCK CHLORINE
If chlorine is low or the water has been heavily used or contaminated, apply Shock Granules according to the product label.
-
RUN THE FILTER AND RETEST
Keep the water circulating while it clears. Clean the filter again if necessary and retest the water before swimming.
Never mix different pool chemicals together. Add each product separately and always follow the instructions on the product label.
Treatment timeline
HOW LONG DOES CLOUDY POOL WATER TAKE TO CLEAR?
Clearing time depends on the cause of the cloudiness, the condition of the filter and how quickly the water balance is corrected.
-
12 to 24 hours
LIGHT CLOUDINESS
Light haze may begin to improve after balancing the water, cleaning the filter and restoring circulation. Continue filtering and retest the water.
-
24 to 48 hours
MODERATE CLOUDINESS
Water affected by low chlorine, heavy use or suspended debris may require one to two days of filtration after treatment.
-
2 to 3 days or longer
PERSISTENT CLOUDINESS
If the water remains cloudy, retest the pH and chlorine, clean the filter again and inspect the circulation system. Do not repeatedly add shock chlorine without testing first.
CLEAR WATER ALL SEASON
KEEP CLOUDY WATER FROM COMING BACK
Regular testing, good circulation and proper filter maintenance prevent most cloudy-water problems before they start.
- Test the Water Regularly Monitor chlorine and pH, especially during warm weather and frequent pool use. 2–3× WEEKLY
- Maintain Chlorine and pH Keep water within the recommended levels shown on your testing kit. 2–3× WEEKLY
- Keep the Filter Clean Clean or backwash the filter when required so it can continue removing debris. WEEKLY / AS NEEDED
- Run the Circulation System Operate the pump long enough to circulate and filter the full pool volume. DAILY
- Brush and Remove Debris Remove leaves, vacuum the floor and brush pool surfaces regularly. DAILY

Frequently Asked Questions
Cloudy water can be caused by low chlorine, unbalanced pH, poor circulation, a dirty filter, heavy pool use, fine debris or early algae growth.
Do not swim until the water is clear enough to see the pool floor and drains, and the chlorine and pH levels have returned to a safe range.
Shock chlorine can help when cloudiness is caused by low chlorine, contamination or early algae. It will not fix poor filtration or incorrect water balance on its own.
Keep the pump and filter operating throughout treatment where your equipment allows. Clean or backwash the filter as debris collects, following the equipment instructions.
Recheck the chlorine and pH, clean the filter and inspect the circulation system. Very fine suspended particles may also require a pool clarifier, even when the water chemistry is correct.
