The flocking phenomenon known as “swimming pool greening” has been observed for decades. The algae that makes up the pools can grow to be massive, often obscuring much of the water’s surface area and sometimes even making it difficult to see through.
Why do some pools still remain cloudy after flocking? What are some preventative measures owners can take in order to keep their swimming pool nice and clear?
The answer will surprise you!

“pool is cloudy but chemicals are fine” is a question that many people have been asking. The answer to this question can be found in the “Why is my pool still cloudy after flocking?” article.

Why is my pool still cloudy after flocking? |

The main reason of murky water is a lack of chlorine. If all of the chemicals are balanced but the water is still hazy, there may be small particles in the pool, in which case you should use a clarifier or pool flocculant before vacuuming it up. If nothing else works, try backwashing your filter, which may be blocked.

As a result, why does my pool get foggy when I clean it?

If you have a sand filter, you should set it to “trash” or “backwash” before vacuuming. The goal is to vacuum the murky water OUT of your pool, since pushing that much unclean water through your filter will not work and will only return the bad water to your pool.

One could also wonder how long the pool remains hazy after being shocked. A hazy pool after shocks is usually just transitory and should disappear within 24 hours. Continue to filter your pool, and if necessary, add a little clarifier, and your pool should be clear in no time. If your pool is still not clear after 24 hours, you may need to dig a little deeper for the answer.

What happens if you add too much clarifier to your pool, too?

When you use too much clarifier, all of the small particles cluster together too much, resulting in a colloidal suspension. When that occurs, everything becomes murky. It will clear eventually, but it will take some time. Run the filter 24 hours a day, 7 days a week until it clears.

Is it possible to have too much chlorine in your water and have foggy water?

If you apply too many pool chemicals, your water will get hazy. High pH, high alkalinity, high chlorine or other sanitizers, and high calcium hardness are examples of this.

Is it possible to clean a hazy pool using baking soda?

NO! Baking soda is a base that raises the pH level dramatically, causing the water to become hazy. If alkalinity is excessive, some individuals may recommend baking soda as a fast remedy, but it is not a trustworthy pool chemical. The only material that should be used to clean a hazy pool is chlorine.

Is there such a thing as too much shock in a pool?

Excessive chlorine exposure may cause asthma, lung discomfort, and perhaps skin and eye irritation. It’s not only unhealthy for you, but it’s also bad for your pool. The pH of the water is lowered by high chlorine levels. So, before you add shock to the pool, be sure to check the PH level.

Is it possible to vacuum my pool while it is in the backwash cycle?

Vacuuming first and then backwashing is usually a smart idea. Backwashing your filter eliminates the dirt and debris that has accumulated. If you don’t backwash your filter, it will gradually get clogged, causing excessive pressure to build up while it is operating.

Is it possible to swim in a hazy pool after being shocked?

Swimming up to your shock level, depending on your CYA, is technically safe if your free chlorine levels are holding up. Remember, even if your free chlorine levels are stable, no one should swim in a foggy pool.

How can I make the water in my pool crystal clear?

Apply Shock and Algaecide on a weekly basis.

Even if you keep your pool’s chlorine and pH levels in check, the water may need a boost to stay clean and sparkly. You should shock or super-chlorinate your pool once a week to destroy any bacteria or algae that may be present.

How long does a pool clarifier take to start working?

Although various kinds of clarifiers have somewhat varied instructions, most function in the same way: For 24 to 48 hours, run your swimming pool filtration system.

Is it possible to use too much flocculant?

Flocculation is the term for suspended particles in water that cause it to seem murky. Flocculants are compounds that assist remove the cloudiness in your swimming pool water and restore its clarity. However, there is such a thing as too much floc. An excessive amount of floc might distract from the aesthetics of your pool.

How frequently should a clarifier be added to a pool?

When should you use a pool clarifier? Pool clarifiers aren’t designed to be used all season, but they may come in handy when the pool is first opened, after an algae bloom, or when dealing with hazy pool water. Follow the label’s instructions, however most pools may be retreated in 5-7 days with a lesser dose than the first time.

Is it possible to use algaecide and shock in the same pool?

You may get rid of the sickly green hue produced by algae development by shocking your pool and adding an algaecide to the water, but you shouldn’t do both at the same time. Chlorine reacts with the algaecide components, rendering them ineffective.

How soon after applying clarifier can you swim?

Time: 20 minutes

What is the purpose of a pool clarifier?

Clarifier is a concentrated chemical that condenses the microscopic particles and germs in your pool into bigger clumps that your pool filter can easily take up. We’re talking about tiny particles that your filter won’t collect or that your skimmer won’t take up.

What is the difference between a flocculant and a clarifier?

The difference between a clarifier and a floc is that clarifiers generate particle sizes big enough for your filter to remove over many days. Flocculants act considerably quicker and form big clumps that clog pool filters, therefore they must be applied differently.

Is it possible to over-chlorinate a pool?

Of course, there is a risk of too much chlorine in pool water. Excessive chlorine exposure may cause asthma, lung discomfort, and perhaps skin and eye irritation. It’s not only unhealthy for you, but it’s also bad for your pool. The pH of the water is lowered by high chlorine levels.

After shocking, how long should I operate my pool pump?

To guarantee proper distribution, run your pump for at least 8 hours at night.

  1. BEFORE putting shock in the pool, pre-dissolve it in a pail of water.
  2. DO NOT DIRECTLY ADD SHOCK TO YOUR SKIMMER (especially if you use a chlorine generator)

When shocking the pool, do you run the filter?

It’s preferable to let the pool filter run for 6-8 hours before applying the shock, and to apply the shock after the sun has set. When you do a pool shock treatment, the efficacy of chlorine is reduced, requiring you to use twice as much chemical or rendering the shock treatment worthless.

In a pool, may bleach be used instead of chlorine?

All you need is bleach or liquid chlorine to get a Conditioner level of 30 ppm-50 ppm. Bleach has the same chemical as liquid chlorine, which may be purchased at your local pool shop or hardware store. Bleach is just somewhat weaker than liquid chlorine in terms of volume.
