Can I Use Clarifier After Flocculant


Using a Flocculant treatment for your pool water is a typical solution for clearing up a cloudy failed inbalance algae-filled pool that won’t be cured by a Pool Clarifier that you would normally use for weekly maintenance after shocking the pool. But it might come in handy AFTER using the floc treatment. Can I Use Clarifier After Flocculant?

Clarifiers are used after Flocculant

Removing light floc left over from quick-settling heavy floc
Floc knocked into suspension vacuuming
High TDS/Salt in H2O prevents flocculation.
Using too much flocculant
Low pH start
Not waiting long enough
Negative charge was not neutralized in light floc by flocculant

 

Turbidity (or cloudiness) of water is caused by fine particles suspended in the water that are leftover from the Flocculant treatment. These particles are typically smaller than two microns and will normally pass through the filter system.

Can I Use Clarifier After flocculant

 

Turbidity (or cloudiness) of water is caused by fine particles suspended in the water. These particles are typically smaller than two microns and will normally pass through the filter system. They are of low density and will therefore be suspended in the water.

Pool Clarifiers can and are used after Flocculant treatment to remove tiny particles left over from the quick-settling heavy floc.

Most particles are negatively charged and repel each other. In order to remove these particles it is first necessary to add a flocculent (positively charged) which will coagulate the fine particles into larger “flocs” by neutralizing the negative charge, allowing the particles to come together and form a floc.

Do not disturb the pool water during this time. Slowly vacuum your swimming pool to waste using a manual vacuum. If your pool gets cloudy while vacuuming take a break and allow the particles to settle once again.

Once the pool is clear, backwash and rinse the filter thoroughly. Using too much pool flocculant can actually make your pool water even more cloudy. Just like any other pool chemical, be sure to follow the manufacturer’s instructions and add the appropriate amount based on your pool’s volume.

Pool Clarifiers are used to collect all the small low-density particles that can be separated from pool water by running through the filtering system.

Too much flocculant means that it will start to stick to itself over and above the bacteria and algae spores that you’re trying to clear. The issue with this happening is that it won’t sink to the bottom. It’ll stay floating in your pool and start to cause more problems, like clogging your pool filter.

 

What is Pool Flocculant?

A pool flocculant is a chemical that helps to remove small particles from pool water, these particles can include dirt, debris, algae, and bacteria. Flocculants work by clumping these particles together helping them settle out so that they can be removed from the pool H2O  ……………………………………………… Read more

 

 

Why isn’t the Pool Flocculant Working?

Reasons Flocculant didn’t Work:

You are using flocculant on living algae-you need to shock your pool with chlorine first to kill algae then settle
You didn’t wait long enough-Flocculant directions have a dozing rate & wait time.
Cloudiness in the pool could be caused by an in-balance ..…………………………………………………… Read more

Why is My Pool Cloudy After Using Flocculant

 

The type of flocculent used will also dictate if a light or heavy floc is formed.

  • Aluminum-based flocs such as poly aluminum chloride (PAC) or Alum will form a heavy floc that settles quickly to the bottom of the pool sometimes leaving small particles above.
  • Cationic Electrolytes that are used in Pool clarifiers and natural flocs will form light flocs and tend to work efficiently by filtering.

The terms “flocculants” and “coagulants” are synonymous with each other; however, the process of clearing cloudy/dirty pools is in fact a two-stage process involving both coagulation and flocculation.

  • Some flocs will be “light flocs” which will tend to remain suspended in the water or even rise to the surface of the pool and are then caught on the filter bed. Algae and organic matter may form lighter flocs.
  • High TDS levels or Salt will also slow up or prevent efficient flocculation.
  • Pool experts recommend after vacuuming and rebalancing the pool water place a clarifier in the skimmer basket to really polish the water and leave it crystal clear.
  • Using too much flocculant means that it will start to stick to itself over and above the bacteria and algae spores that you’re trying to clear.
  • The issue with this happening is that it won’t sink to the bottom. It’ll stay floating in your pool and start to cause more problems, like clogging your pool filter.

 

Does Pool Flocculant Reduce Hardness?

Yes, a flocculant treatment will help settle out free-floating minerals such as calcium & remove them by wasting them from the system and replacing the H2O lost from the pool. Flocculants can only cause minerals out-of-solution to stick together so dissolve calcium can’t be removed from the pool H2O …………………………………….. Read more
