Swimming in your own private, crystal-clear pool on a warm summer day is one of life’s greatest pleasures. However, what if the water in your pool isn’t as crystal clear as you’d like it to be? Perhaps your pool’s water appears murky and cloudy after the season has begun, making it unappealing to swim in. The solution is to use the best pool clarifier, and you will have crystal clear water in your pool within a few hours. This is a common problem faced by most pool owners. The good news is pool clarifiers are a simple solution that you simply add to the water and watch it do its thing. After a few hours, your pool’s water will be crystal clear. To compare some of the best and most popular clarifiers on the market, we reviewed five top pool water clarifiers.

What is Pool Clarifier?

Adding a clarifier to your pool is an easy way to get rid of tiny particles and bacteria that are too small to be picked up by your filter. Microparticles are those that your filter or skimmer cannot pick up because they are too small.

Polymers in pool clarifiers act as coagulants to remove foreign particles from the water. When you add a clarifier to your pool, you’re introducing positively charged ions into the water, making it cleaner. Positive ions in your pool attract suspended particles with a negative charge, causing them to form clumps that can be removed by the pool’s filtration system, like tiny magnets.

What You Need to Know About Pool Clarifier

Summer time is almost there, and it is time to prepare your swimming pool to cool off. The worst thing you don’t want to see is murky pool water with cloudy water and algae. In the past, having cloudy swimming pool water and algae was the worst thing you would want to see in your pool good thing a pool clarifier was invented. You can have crystal clear water fast and easy.

Ask your pool retailer or manufacturer for a recommendation if you’re looking for a pool clarifier. There are several high-quality options available. Keep the following things in mind before purchasing the best pool clarifier.

Pool’s Requirements

The problem isn’t just cloudy water. If this is the case, you may have algae as well. Algae growth and sulfate concentrations are two other causes of murky water.


If you’re in a hurry to clear your cloudy pool water, a flocculant might be a better option than a clarifier.

Filtration System

Last but not least, choose a purifier that can run your pool filter for 8-12 hours every day as a final word of caution.

You should run your pool’s filtration system long enough to clean the water every day thoroughly. Water that is not being filtered builds up dirt and cloudiness when circulation isn’t working properly in your pool. Below are some of the things you need to know when buying the best pool clarifier:

How to Choose the Best Pool Clarifier?

Start by asking your local pool retailer or the manufacturer of your swimming pool for a recommendation when you’re looking to buy a clarifier. There is a slew of reputable companies to pick from, and each one will do the job.

Here are some things to keep in mind when deciding whether or not to buy:

  • Specific problems with your pool. Is it just cloudy water that you are dealing with? You may have algae, as well. Sulfur levels and algae growth can also cause cloudy water.
  • Consider using a flocculant instead of a pool clarifier when you want things to happen if you have less than 24 hours to treat your cloudy pool water because some clarifiers take longer to work than flocculants.

Why Your Pool Might Be Cloudy?

Besides having bacteria and dirt, there are other reasons why your pool might be cloudy.

The Temperature. Pollutants are often found in pools that are overflowing with rain, leaving behind traces of film or beaten down leaves.

Chemical overload. As a result, you must monitor the pH of your pool regularly. A pool chemical overdose can be just as harmful as a pool chemical underdose. A Clogged Filter. The problem could also be a faulty filter (sand, DE, or cartridge) that isn’t being properly maintained. Is it doing what it’s supposed to be doing?

Flocculant vs Clarifier

Clearing cloudy pool water can usually be accomplished using a flocculant or a clarifier if you’ve done any research on the subject. However, the two products differ in the way they deal with the large, manageable clumps of tiny particles:

The use of a clarifier will result in bundles of clarifiers floating on top of the water and passing through the filtration system. In contrast, flocculants cause the bundles to sink and require a vacuum to remove them from the bottom of the pool. Call a pool professional right away if your pool’s water is discolored or cloudy. To figure out what’s causing your pool’s cloudiness, have a water sample on hand.

What If Your Pool is Still Cloudy After Clarifying?

Using a clarifier or pool flocculant and then vacuuming your pool is necessary if the water is still cloudy despite all the chemicals being balanced. If that doesn’t work, you might want to give backwashing your filter a shot.

Frequently Asked Questions – (FAQ)

How to use a pool clarifier?

Follow the three easy steps below in using a pool clarifier:       
·         Make sure the pH level of your pool is correct.
·         Be sure to follow the manufacturer’s recommendations for how many clarifiers to use.
·         Until the water is crystal clear, keep the pool filter running nonstop.

When to use a clarifier?

It is not recommended to use a pool clarifier all season long. Instead, it is best to use it after an algae bloom, when the pool water is cloudy, or when the pool is just opening. Pools can be re-treated after 5-7 days, with a lower dosage than the initial one, following the label’s instructions.

Can you make a homemade clarifier?

Yes, you can, but it is not as effective as the pool clarifier you can buy on the market today. It’s called the “BBB Method,” and it uses baking soda, Borax, and bleach to stabilize your pool’s chemical composition.
To use it correctly, you’ll need a testing kit. Once you’ve checked the levels, you can raise the pH with Borax, the total alkalinity with baking soda, and the chlorine with bleach.

How long does it take for the pool clarifier to work?

Using a pool water clarifier can take anywhere from two to three days, depending on how cloudy your pool is. Your water needs to be balanced, and your water filter must be running constantly while the clarifier is working. And if you’ve got an algae problem, you’ll need to fix that first before using a clarifier in your water.

What Happens if I put too much clarifier in my pool?

Excessive pool clarifiers can result in cloudiness in your pool. Partially drain your pool and refill it with fresh water if this happens. Afterward, you can remove the remaining pool clarifier overload by filtering it out, but be careful, as too much clarifier can cause your filter to become clogged up.

Why Should You Use a Clarifier?

Despite the fact that swimming in a cloudy pool may seem like a no-brainer, it can be highly hazardous.
There are several good reasons to clean up your pool before your next pool party, depending on the source of the murkiness.
Avoid Water-Related Ailments: If the water in your pool is dirty, cloudy, or otherwise unclean, it could be hiding something hazardous. According to the Centers for Disease Control and Prevention, cloudy pools are a breeding ground for E. Coli and Giardia bacteria, both of which can cause diarrhea, pink eye, ear infections, and respiratory infections.
The Health of the Environment and Its General Appearance: You and your family could be infected by mosquitoes (and other pests) that carry deadly diseases if the water is dirty or contaminated. It’s also worth noting that an unsightly, dingy green pool is a bad investment (or popularity in the neighborhood). 
Swimmer Protection: Because of the reduced visibility and murky water, swimming pool accidents and drownings are more likely. It’s terrifying to think about jumping into a watery grave and hitting someone who is swimming beneath the surface or, even worse, not being able to see someone who is in distress.
