Cloudy blue pool water is unsightly, unpleasant, and even potentially dangerous. If you’ve noticed a murky or cloudy pool, then you should consider getting it cleaned or maintained by a professional pool service in Atlanta.
But in this article, we’ll answer the question of “why is my pool cloudy blue”and what you can do about it.
Seven Reasons Your Pool is Blue But Cloudy
If your pool is blue, everything should be good, right? Well, not so fast. Obviously, if the water isn’t clear, there’s a deeper issue somewhere. Here are the potential culprits:
1. Faulty Filtration System
If you’re asking yourself “why is my pool blue but cloudy?” then one likely reason is the filter. If your pool filter is not working properly, your pool is going to be cloudy because the water is stagnant.
Most cloudy pool issues are due to filters that simply aren’t doing their job. This could be due to a faulty pump, a filter that’s clogged, or maybe the fact that the filtration system just hasn’t been running long enough.
2. Incorrect PH Levels Or Chlorine Levels
The pH and chlorine levels are another culprit for murky pools. Chlorine depends on the right pH levels to stay what is called “free.”
If there’s not enough free chlorine, then it forms something called chloramine, and this chloramine is what gives the pool a cloudy texture.
Therefore, the recommended level of chlorine combined chlorine level should always be just below 0.5 ppm or 0 ppm.
In addition, a pH of over 7.8 will make the chlorine ineffective at killing off bacteria. This affects the water’s quality and puts you at greater risk for algae.
3. High Levels Of Alkalinity
The total alkalinity (TA) is closely associated with cloudy pools. If it’s too high, it makes the pH balance off, which creates what’s called scaling due to calcium. So, if you have higher than 200 ppm of TA, this could be the reason that your pool is blue but cloudy.
4. Too Much Calcium Hardness
Calcium hardness (CH) is the total calcium dissolved in the pool water. If the levels of calcium are high, then they will be unstable. And any imbalance in TA or pH will affect them.
You want to aim for 100 to 400 ppm of CH. If it goes over 400 ppm, then calcium scaling can occur and cause cloudiness.
5. Particles Left Behind By Swimmers
People in the pool can leave behind particles from sunscreen, sweat, and other bodily oils. If these add up enough, they’ll start to make a visual difference, and you’ll notice a more cloudy pool.
6. Debris From The Environment
Flowers, twigs, trees, buds, and other things from nature can land in your pool. If you don’t have great circulation, these can eventually cause murkiness.
Rainwater has nitrates, phosphates, and other elements that turn your pool cloudy. In addition, a lot of rainfall can dilute the amount of chlorine in your pool, so it’s not as effective in keeping it clear.
What to Do if You Have a Cloudy Pool?
Whether you should clean out your pool, drain your pool, or simply have some maintenance on the filtration system, it’s difficult to tell.
For that reason, it’s best left to the professionals. So stop asking “why is my pool water blue but cloudy” and learn the reason in a few hours straight from the experts.
