Pool chemicals could be out of balance or the pH might be off. Chlorine levels and the right pH are key to keeping a pool clear. If a pool's pump or the filter isn't working right, the water may look murkier than usual. Storms or increased rainfall can affect your pool.
Improper pH levels can affect your chlorine and the other chemicals in your water. High levels of pH can cause calcium build-up and scaling which leads to cloudy pool water. Low levels of pH can cause your chlorine to become overly reactive and quickly depleted.
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.
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.
Excessive levels of pool chemicals can cause your water to become cloudy. High pH, high alkalinity, high chlorine or other sanitisers, and high calcium hardness are all common culprits.
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.
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. If after 24 hours your pool is not clear, then you may need to look a little deeper for the solution.
Adding a recommended dose of shock to your pool can clear it right up. Poor circulation or filtration can contribute to cloudy water. Make sure your pump and filter are working properly.
Shock the pool with a high level of chlorine or bromine to rapidly return the pool water to a balanced level. Imbalanced alkalinity and pH also could result in cloudy water, and it can be a safety hazard.
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.
1) After shock - Sometimes pool water looks cloudy right after you apply shock granules such as cal-hypo, or liquid shock, but rest assured it's only temporary. This could be due to change in water balance – meaning your pool water temporarily goes off balance when adding these products.
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.
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.
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.
If your pool is just mildly cloudy and you are not in a rush to clean it out, a clarifier may be your best bet. A clarifier requires less work and less water but can take to two to three days to achieve the results you are looking for.
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.
Vinegar contains acetic acid which makes it a great disinfectant. It is also acidic in nature hence removes dirt, grease and mineral deposits. If used in the right amount, its acidic nature also plays a role in lowering the pH of pool water.
Short answer: yes. Longer answer: it depends on the formulation. The label on every bleach bottle should tell you the ratio of sodium hypochlorite (and available chlorine) in the bottle to everything else. A higher percentage is generally better, as you'll need to use less bleach to treat your pool.
The Bottom Line
Adding a Magic Eraser sponge to your pool skimmer is not a professional-approved pool maintenance technique. It may remove some algae, but it may also cause other problems you're not anticipating – including serious health risks.
Low pH water will cause etching and deterioration of plaster, grout, stone, concrete and tiling. Any vinyl surfaces will also become brittle, which increases risk of cracks and tears. All of these dissolved minerals will hold in the solution of your pool water; which can result in staining and cloudy pool water.
Rule of thumb is to do the PH first. And do not bother to drive to pool store to spend the extra money for a PH DECREASER. Buy a plain baking soda for 50cents a pound in Walmart! Chlorine will not work fully until your PH is in the proper range.
