Flocculants for swimming pools

How do I know if I need to use pool flocculants and when is the ideal time to apply them?

Detecting the need to use pool flocculants is simple: if your pool water looks cloudy, milky or whitish, despite having the correct chlorine and pH levels, it is time to act. Very fine particles are not retained by the filter, and that is where flocculants come into play. At Pools and Products, we recommend applying them when turbidity is evident or as part of shock maintenance. It is crucial that before starting treatment, you verify that pH levels are between 7.2 and 7.6 to ensure maximum effectiveness of pool flocculant products.

What are the types of pool flocculants available at Piscinas y Productos and how are they different?

At Pools and Products, we primarily offer two types of pool flocculants to suit your filtration system and application preferences. Knowing the types of pool flocculants will help you make the best decision when purchasing pool flocculant:

• Liquid flocculant for pools: It is ideal for shock treatments or recovery of very cloudy waters. It is dosed directly into the pool or, in some cases, into the skimmer. Its action is fast and effective, acting by precipitation.
• Flocculant in cartridges or tablets: These are generally used for continuous maintenance. They are placed directly into the skimmer and dissolve slowly, offering a long, consistent dosage to maintain clarity. They are very comfortable and reduce the need for daily application.

Does liquid pool flocculant affect the pH of the water and how should I store it to maintain its effectiveness?

One of the great advantages of our liquid pool flocculant is that it has been formulated not to significantly alter the pH of the water, as long as the recommended dosage is used. This is vital because the pH must be balanced (between 7.2 and 7.6) for flocculants to work properly. Regarding its conservation, to guarantee maximum effectiveness and useful life of the product, you must:

• Keep it in its original container, tightly closed.
• Store it in a cool, dry place, away from direct sunlight.
• Make sure it is out of the reach of children and pets.

How is the application of a pool flocculant carried out safely and effectively so as not to damage the filter?

Applying the flocculant correctly is essential. For most pool flocculant products, the application process varies whether you use the liquid version (shock treatment) or cartridges (maintenance):

• Shock Treatment (liquid flocculant): Stop the filtration system, distribute the necessary dose of liquid pool flocculant over the surface of the water, and let the product act for several hours (overnight is ideal). The flocculant will precipitate the particles to the bottom. Then, remove the dirt with a manual pool cleaner and make sure the selector valve is in the empty position (if it is a sand filter) to avoid overloading the filter.
• Maintenance (cartridges): Simply place the cartridge in the skimmer (one for each certain volume of water, depending on the manufacturer) and let the filtration system do its job. The product will be released slowly.

If I am already using a clarifier, does it make sense to buy pool flocculant or are they the same product?

Although both seek to clarify the water, they are not exactly the same product nor do they act the same. Clarifiers are usually less powerful and are designed for maintenance use, helping the filter retain very small particles. Flocculants, on the other hand, are a more intensive and shock treatment, grouping the particles into large flocs that fall to the bottom. If your water is very cloudy, you need a powerful treatment like flocculant. If the water is slightly cloudy, a clarifier may be sufficient. In our selection of pool flocculant products you will find the most suitable option for your situation.

Is it necessary to turn on the purifier immediately after applying liquid pool flocculant?

No, in fact, it is strongly recommended to turn off the purifier and the pump after applying the liquid pool flocculant. The key to the flocculation process is to allow the clumped particles (flocs) to completely precipitate to the bottom of the pool by gravity. This requires a period of water inactivity, generally 8 to 12 hours. If you keep the purifier on, the water will keep moving and prevent the particles from settling, nullifying the desired effect of the flocculant. After this time, you can clean the flocs with a pool cleaner.

What happens if I apply too much pool flocculant?

An excess of flocculants for swimming pools can be counterproductive. If you add too much product, the consequences can be:

• Persistent turbidity: Excess flocculant can make the water cloudy again or form a gelatinous layer that is difficult to remove.
• Filter overload: If you use a filter-compatible flocculant (such as tablets), too much of it can clump the filter sand or saturate the cartridges, reducing filtration efficiency and may require immediate backwashing or even replacement of the filter media.

Therefore, when purchasing pool flocculant, always follow the manufacturer's specific dosages, based on the cubic meters of your facility. Precision is the key to successful treatment.

Are pool flocculant products compatible with all types of filters?

Compatibility is a very important point to consider before purchasing pool flocculant. Liquid types of pool flocculants, which act by precipitation to the bottom, are generally safe for all filters, since dirt is manually removed to the bottom and does not pass through the system. However, flocculants in cartridges or tablets (designed for continuous filtration) are primarily intended for sand filters.

• Sand filters: They are the most compatible with both formats.
• Cartridge or diatom filters: The use of flocculants can quickly saturate and damage these filters. If you have one of these systems, opt for liquid pool flocculant and remove settled debris directly to the drain.

How often should I buy pool flocculant? Can it be used weekly?

The frequency with which you should purchase pool flocculant and apply it will depend on the quality of your water and the type of product you choose. Flocculant is not designed for consistent daily or weekly use. It is mainly used in the following situations:

• Shock Treatment: When the water is visibly cloudy, usually after heavy rain or heavy use.
• Preventative Maintenance: If you use cartridges or tablets, they offer extended dosing that can last for weeks, ensuring consistent clarity. They are replaced according to the product instructions.

If you need to use flocculant very frequently, it may be a sign that there is an underlying problem with the chemical balance of the water or the filtration system, so we recommend checking the pH and chlorine.

How do I remove liquid pool flocculant after the particles have settled to the bottom?

Once the liquid pool flocculant has done its job and the dirt has settled to the bottom, you must carefully remove it to prevent the particles from re-dispersing. The best method is to suck this layer of flocs directly into the drain, preventing them from passing through the main filter, which is achieved by putting the selector valve in the 'Empty' or 'Drain' position (if your filter allows it) and using a manual pool cleaner with slow movements. This ensures that dirt is expelled from the pool system, leaving the water crystal clear.
