You can add Clarifier and/or Flocculents, in the correct dosage, to bond the microparticles. This will allow the particles causing your cloudy pool to become big enough to filter (Clarifier) or heavy enough to sink (Flocculent) to the bottom of the pool to be vacuumed. We recommend this Clarifier and this Flocculent.
Poor water chemistry causes most cases of cloudy water. Test your water to make sure it's properly balanced. Chlorine issues often cause cloudy water. Adding a recommended dose of shock to your pool can clear it right up.
How long does it take for a cloudy pool to clear? Depending on how cloudy your water is, it may take 2-3 days for your water to clear. If you're using a clarifier, you'll need to run your filter 24/7, keep your water chemistry balanced, and add the proper amount of water clarifier every other day until it's clear.
When the pH levels are imbalanced, it renders the free chlorine ineffective and the levels decrease. Too little free chlorine forms chloramine and it is this combined chlorine that results in your pool's cloudy appearance.
In theory, if you have a cloudy swimming pool, you can add chlorine to “shock it” and clear things up. Chlorine will get the job done. But, the amounts may vary and you may have to really pound the pool with chlorine to get the water totally clear.
Baking Soda
Most remedies call for adding additional chlorine into the water. If your water's pH balance is between 7.2 and 7.5, however, you can add baking soda to the water to help clear it up. This serves as a replacement for chlorine because baking soda is a natural cleaning agent.
For the most part, yes. It can be unattractive and it should be addressed, but it is mostly safe to swim in cloudy water. The only exception would be if the pool is cloudy because there are too many chemicals in it. This pool water would be unsafe to swim in and should be avoided.
The simple answer is No. Baking soda cannot be used to clear up a cloudy pool because it is a base. Bases raise PH levels, which causes the water to turn cloudy. Some people suggest using baking soda as a quick fix to high alkalinity levels, but it's not reliable as a pool chemical.
The presence of too much algaecide can lead to a foamy pool water. Small bubbles will begin to be produced as the water is pushed through the return jet and back into the pool. Do not confuse these bubbles and foam with another common problem, which is air in your pool lines.
To maintain a clear sparkling pool add 4 fluid ounces of Water Clarifier per 10,000 gallons of water weekly. If the pool is cloudy due to dust or to high hardness of the water, add 32 fluid ounces of Water Clarifier per 10,000 gallons of pool water.
If the chlorine smell is very strong, however, you may soon spot “red-eyed” swimmers emerging from the pool. That's when the pool water is assumed to have “too much chlorine” in it. Ironically, a strong chemical smell around the pool and “swimmer red eye” may be signs that there is not enough chlorine in the water.
Cloudy or milky swimming pool water is caused by seven main issues: improper levels of chlorine, imbalanced pH and alkalinity, very high calcium hardness (CH) levels, faulty or clogged filter, early stages of algae, ammonia, and debris.
With a rain storm, any number of contaminants can be washing into your pool – acid rain, pollen, insects, tree droppings, dust, sand and even phosphates. Any one or combination of these things in rain can make your pool cloudy.
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity.
Some of the best natural homemade pool clarifiers include baking soda solution, bleach, white vinegar, lemon juice, rubbing alcohol and borax. Compared to commercial chemical clarifiers natural ones have enzymes that break down the dirt in the water making it easy and cheap to filter them out.
Skim the top of the pool for debris that may have settled on the pool surface. Add one pound of diluted granular shock to the water for every 7,000 gallons of pool water. Run the filter for 24 hours and retest the water. The slimy looking film can be an early onset of algae.
The pH of a pool should be between 7.2 and 7.8, with 7.6 being the ideal balance. Levels below 7.0 indicate acidic water. Levels above 7.8 mean that the water is too alkaline or basic. Both instances can lead to a cloudy pool.
How to fix cloudy pool water caused by poor filtration. When a pool clarifier doesn't work and the water chemistry is balanced, then the cause of cloudy pool water is likely mechanical. The range of pump and filtration problems starts with simple human error and extends to worn-out or broken parts.
Two forms of vitamin C, ascorbic acid and sodium ascorbate, will neutralize chlorine. Neither is considered a hazardous chemical. First, vitamin C does not lower the dissolved oxygen as much as sulfur-based chemicals do. Second, vitamin C is not toxic to aquatic life at the levels used for dechlorinating water.
The best chlorine neutralizer available for swimming pools is still sodium thiosulfate.
After Adding pH, Alkalinity and Clarifier
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals.
Never add chemicals at the same time, whether you're balancing the water, shocking the pool, or adding a specialty chemical. For most water balance changes, the pump needs to run on the high setting for at least four hours before you can add another chemical or retest the water.
Add 1 part white vinegar to every 10 parts of water to make the defoamer. For example, a 100-gallon kiddie pool would require 10 gallons of vinegar to work effectively. White vinegar also works as a defoamer in hot tubs, spas and carpet steam cleaners.
