Remember that high alkalinity, high pH, and high calcium hardness can cause cloudy water. If there is a problem with the chlorine, pH or other chemical levels in your pool, adjusting those levels can be enough to correct the cloudiness.

Similarly, it is asked, does high pH cause cloudy pool water?

The pH Is Too High - When the pH in your pool water exceeds 7.8, the chlorine reacts less quickly and is less efficient at killing off algae, often causing cloudy water. The Total Alkalinity (TA) Is Too High - If the total alkalinity of your pool water is tested at higher than 200 ppm, cloudy water can result.

Additionally, can too much chlorine cause cloudy water? An excessive amount of pool chemicals can cause your water to be cloudy. That includes: high pH, high alkalinity, high chlorine or other sanitizers, and high calcium hardness.

Hereof, how long should it take to clear a cloudy pool?

In most cases, a cloudy pool after shocking is only temporary and should clear up within 24 hours. Keep filtering your pool, add a little clarifier to help, and your pool should be clear in no time.

Will baking soda clear up a cloudy pool?

NO! Baking soda is a base and will hugely increase the level of pH, which actually causes the water to turn cloudy. Some people may suggest using baking soda as a quick fix if alkalinity is high, but it is not a reliable pool chemical. Chlorine should be the only substance used to clear a cloudy pool.

Why is my pool cloudy after shocking it?

5 Reasons Why your Pool is Cloudy after Shock
Alkalinity is closely related to pH, and when it's too high, it can prevent you from lowering your pH easily, and it can easily throw off bicarbonates, which make the pool cloudy. Use pH Decreaser to reduce Total Alkalinity if the level is over 100 ppm.

Will chlorine tablets clear a cloudy pool?

To get rid of all the gross and dangerous crud in your cloudy pool water, shock your pool. This mega-dose of chlorine (or non-chlorine shock. for pools that use other sanitizers) will eliminate cloudiness caused by bacteria, organic contaminants, and algae.

Can you shock your pool during the day?


What Is the Best Time of Day to Shock a Swimming Pool? Shock your pool late in the evening or at night, when the sun is down, to make sure free chlorine will stay in your water longer. Ultraviolet (UV) rays from direct sunlight greatly reduces free chlorine levels, so shocking during the day will not be very effective.

How does pool clarifier work?

Pool ClarifiersHow do they Work? Pool clarifiers are polymers that act as coagulants on suspended particles in the water. Specifically, clarifiers impart cations or positively charged ions to the pool, which are attracted to negatively charged suspended particles.

Can you swim in a cloudy blue pool?


Double check the pH and alkalinity, and be sure the chlorine level is below 5 ppm. Even if the water is not completely clear, but more of a cloudy blue-ish color, you could allow limited swimming. If the water is so cloudy that you cannot see the pool bottom however, that poses several safety risks for swimmers.
