This particular flocculant is best used after applying algae treatment in your swimming pool. I also like that it does not affect the pH level of your pool during the application. Furthermore, it is also safe to use this product in any type of swimming pool and filter.

In terms of its dosage, every 8 ounces of this can treat 10000 gallons of pool water. So, if you buy 1 bottle, it can treat a total of 40000 gallons of water in your swimming pool. Not bad for a flocculant which cleans the debris in your pool and makes the water super clear at an affordable price.

I am amazed at how this product kills and prevents pool algae while turning the cloudy pool into more crystal-clear water. Unlike other products where you need to purchase the algaecide and the clarifier separately, this product combines the two and will definitely save you money.

I also like that it’s non-foaming and the pool can be used immediately after the treatment. You only need around 15 minutes of waiting and you can use the swimming pool after. This is different from other clarifiers or flocculants for that matter where you need more time before using the pool again.

Lastly, this product can also be used in any type of pool. So, if you have a big or mall pool, a spa, or a hot tub, it does not matter. This product will help you in cleaning and preventing algae while keeping the pool water crystal-clear at the same time.

Even though this is an overpriced product, I am still recommending it for purchase because of its quality and the type of results it brings to your swimming pool.

Other Important Factors to Consider


What is a pool clarifier?

In general terms, a pool clarifier is being used when pool owners want to have crystal-clear bluish water in the pool. In other words, a clarifier is needed when you have a cloudy pool that has a large presence of algae and other unwanted debris.

Although it may feel like its generally safe to swim in a cloudy pool, the danger cannot be underestimated especially when it comes to the health of the pool users. The pool clarifier then plays an important role in removing all unwanted debris in the pool, thus improving the clearness and clarity of the pool water.

How does pool clarifier work?

Making the pool water crystal-clear and clean is the end product of using a pool clarifier in your swimming pool. But how does it work? When your pool water is being treated, all the dirt and grimes in the pool are collected and clump together by the pool clarifier.

Once all the dirt and grimes are grouped together, it will then float to the surface of the pool water which in turn will be captured by the pool’ filter system. This will make your pool water clean while also increasing its clarity.

To use the clarifier, it is important to know the reasons behind the pool water’s cloudiness. The chemical imbalance in your pool and a clogged filter are some of the few reasons that turn your pool water into cloudy. The weather, specifically the rain, also leaves chemicals and debris that can increase the cloudiness of your pool water.

The presence of algae is also another reason for a pool water’s cloudiness. Furthermore, it is important to remove the algae from the pool using other treatments before applying the pool clarifier.

It is also important to balance the chemicals in your pool before applying the pool clarifier. You have to know the alkalinity, calcium hardness, and the high pH of your pool before starting the treatment.

After that, follow the instructions found in your pool clarifier diligently in terms of the overall process of the treatment. Be sure to put the exact dosage of the pool clarifier in the swimming pool. Applying too much clarifier in pool might affect its effectivity to produced the much-needed result you want.

The next thing do is to run your pool’s filtration for 24 hours to increase the effectiveness of the pool clarifier. This will improve the circulation and the filtration of your pool while also checking the pH and chlorine levels during the process.

What is the difference between a clarifier and a flocculant?

A clarifier and flocculant work the same in so many ways in cleaning the swimming pool and turning a cloudy pool with crystal-clear water. However, the main difference between the two is how they collect the dirt and the process of removing it.

A clarifier collects and group together all the dirt and unwanted grime in the pool and makes it float on the surface. The pool’s filtration system will then capture all the dirt making the pool clean.

A pool clarifier will be a great help in the pool’s filtration system in capturing and collecting all the unwanted dirt in the pool. However, there is also a chance that the huge volume of dirt will be stuck to the filter which might also affect the overall cleanliness of the pool. Be sure to check the pool’s filter system from time to time.

Meanwhile, flocculants clump together all unwanted dirt and grime and sink them down to the pool floor. The pool owner will then proceed to vacuum all the dirt on the floor in order to make the swimming pool clean and free from dirt.

With this information, it is better to use a flocculant when there is too much debris or algae in your swimming pool. Using a flocculant also requires more time for you with the needed cleaning and vacuuming of the pool floor after the treatment.

Sometimes you also need to take out all the water in your pool after a flocculant treatment. Be sure to prepare in replacing the pool water immediately after the treatment process. As a swimming pool flocculant tips, use this substance only if the pool is too dirty and you have the time to vacuum it after the treatment.

Why do you need a pool water clarifier?

There are so many reasons why you need a pool water clarifier in the pool and these are listed below:

Bacteria and Algae Prevention – Applying a pool clarifier regularly prevents small particles from developing into a bigger group of bacteria and algae. Please take note that these small particles when not clean regularly will then form into a much bigger bacteria which in turn contaminate your pool and makes it look dirty.

Cleaning and Maintenance – Regularly using a pool clarifier as part of the cleaning and maintenance of the pool will help every pool owner in so many ways. For one, it will make the job easy in terms of vacuuming or scrubbing in the swimming pool.

How much clarifier to put in the pool?

Different brands have different dosages in the treatment process of your pool water. It also depends on the size and the type of pool you have.

The most important thing is to follow the full instruction indicated on the brand that you are using. Failure to do so might affect the performance of your pool clarifier in terms of clean the pool water and making it crystal-clear.

How long does a pool clarifier take to work?

Depending on the brand, there is no fixed time for a pool clarifier to work its magic and make the pool water clean. A lot of brands are claiming that their product can clean the pool and make it crystal clear at the quickest possible time.

However, the most important thing to do is to follow the full instruction needed with your specific pool clarifier brands. Whether its 24 hours or 48 hours, it does not matter as long as it meets the desired results you wanted in the swimming pool.

How to care and maintain?

Luckily, a pool clarifier does need too much caring and maintenance after use. All you have to do is keep it in a safe place where the temperature is normal. It is also important to place it in a storage that is unreachable to children.

What is the warranty?

The warranty for a pool clarifier varies depending on the manufacturer or the company. Some offer different warranty terms than the other. The most important thing to do is knowing the terms of the warranty before buying it.

The warranty serves as the buyer’s protection if in case there is a problem or malfunction in the product they buy. The warranty is an important part of the sales process which the buyer should never forget.

Where to buy?

Buying a particular brand of pool clarifier is easy as it is being sold in the nearest store in your area. If you want to buy online, there is a lot of online stores selling original pool clarifiers such as Amazon, eBay, Rakuten, and other online companies.

There are also companies that have their own online stores where you can buy their pool clarifiers. Please be reminded to buy only at authorized retailers to avoid buying fake products and counterfeits.

When should a clarifier be used?

Using the pool clarifier weekly will help in keeping your water clean and crystal-clear. It is also best to use the clarifier when you began to notice algae slowly forming in your pool and when the pool water becomes dirty.

As a reminder, it is important to put only the exact amount of pool clarifier as stated in the instruction of your brand. Putting a lot will sometimes makes the dirt spread around instead of clumping it together.

If you noticed that the clarifier is not working or not producing the desired results, please check the pool’s filter. If it is clogged, then the filter to make it work properly and you will begin to notice the results that you wanted.

If the situation remains the same, be prepared for deeper cleaning and scrubbing of your pool before using the pool clarifier again.

Why the pool water gets cloudy?

There are several reasons why your pool gets cloudy and the most obvious is when your pool’s filter is clogged or not functioning well. When the filter is not doing its job, then the pool water becomes cloudy in no time.

When there are too many chemicals put in the pool, it might also contribute to dirty and cloudy pool water. Always make sure to regularly check the pH levels of the swimming pool to know if there is a chemical imbalance.

Sometimes, the weather can also contribute to the cloudiness of the pool water. Constant raining will bring unnecessary debris and pollutant to the pool water which makes the water dirty and cloudy.

Finally, when there is the presence of algae or other bacteria in the pool, unable to remove it will make the water cloudy at the soonest possible time.

Is there such a thing as a homemade clarifier?

As far as I know, there is still no one who has developed a homemade clarifier that can match the effectiveness of the original pool clarifier in cleaning the pool. It is hard to substitute pool clarifiers which have been manufactured and tested a lot of times to produce the much need result in cleaning and increasing the clarity of the pool water.

Although there are some people who have provided samples of their homemade clarifier, I am not recommending it as they have not been tested to work on the swimming pool. It is not worth the risks and may bring more problems to your pool.
