The Best Flocculant: Our Picks
Guide: Questions you should ask yourself before buying flocculants
What is flocculant suitable for?
The use of flocculants is recommended for greenish water, and flocculants should also be used routinely.
Can I also use flocculant with a "float"?
When can I swim in the pool after use?
With flocculant cartridges, the active ingredient is released gradually, so there is never too high a concentration in the pool.
When using liquid flocculant, however, you should wait 3 - 5 hours.
How much does flocculant cost?
|Flocculant liquid||0.7 - 2.1 Euro/100g|
|Flocculant cartridges||5 - 16 Euro/100g|
For liquid flocculant, the amounts range up to 2 Euro/100g, whereby the different manufacturers charge very different prices. Alternative flocculant cartridges are available from 5 euros/100g and are comparatively expensive.
What are the alternatives to flocculants?
|Vitamin C||As a home remedy as a powder against green water, VItamin C does not do badly, but a comprehensive binding of the smallest parts does not happen.|
|Chlorine||Chlorine is the number 1 pool cleaning agent, which also helps with optical impurities. However, the smallest particles are not made filterable.|
Each method has certain advantages that are not to be sneezed at. Both chlorine and vitamin C powder are good alternatives to clean your pool. However, flocculant seems to be superior to the others in many criteria. Flocculant is also used by many specialists and professionals because it gives the best results.
Decision: What types of flocculants are there and which one is right for you?
If you want to clean your pool with flocculant, there are two alternatives you can choose between:
- Liquid flocculant
- Flocculant cartridges
The way the different flocculants are used each bring advantages and disadvantages. Depending on what you prefer and how you want to clean your pool, a different type is suitable for you. The following section will help you decide.
What are the characteristics of liquid flocculants and what are the advantages and disadvantages?
Liquid flocculants usually consist of aluminium hydroxichloride or cationic polymers. Depending on the active ingredient, they can be added directly to the water, or they must reach it via a "float".
These are characterised by the fact that they can be easily portioned in larger pools and when touching up particularly dirty water due to their liquid form and thus ensure an optimal result.
However, you must be aware that you will not be able to use the pool for several hours due to the high concentration. Therefore, you should pay attention to a good time for the application.
What distinguishes flocculant cartridges and what are the advantages and disadvantages?
Flocculant cartridges often use metal salts such as aluminium sulphate and are characterised by relatively easy handling. They are placed in the skimmer at the edge of the pool and release the active ingredient only gradually.
The pool is cleaned and you can bathe in the meantime. They are therefore very suitable for routine cleaning. However, the prices are quite high, and for larger pools you sometimes cannot avoid costs, unlike with the precise liquid flocculant.
Buying criteria: Use these factors to compare and evaluate flocculants
In the following, we will show you which aspects you can use to decide between the many possible flocculants. The criteria you can use to compare flocculants with each other include:
- Liquid or solid
- Active ingredient
- Duration until the pool can be used again
- Filter type
In the following paragraphs we will explain what is important in the individual criteria.
Liquid or solid
Depending on the size and pollution of the pool, you can choose between two types. Liquid flocculants are suitable for small and very dirty pools. Whereas solid flocculants are particularly suitable for clean as well as larger pools due to their slow duration of action and pre-portioned quantities.
Different active ingredients in the flocculants affect the pool in different ways. Aluminium sulphate, for example, provides an additional layer in the sand filter.
This can initially improve the filtering performance, but leads to more sludge and is only effective in a certain pH range. Whereas polymers, depending on the load, can be used regardless of ph.
Duration until the pool is used again
The duration until the pool is used again varies with the type of flocculant. The process of cleaning the pool starts immediately with liquid flocculant, here you can only use the pool again several hours later.
Liquid flocculant is suitable for repairing the pool after the winter.
Flocculant cartridges do not have this problem, but the cleaning process is also slower. Here you can swim again immediately. However, flocculant cartridges are more suitable for routine use.
To keep the pool moving and to clean the water, most pools have filter systems. A general distinction is made between sand and cartridge filters. The latter are much cheaper to buy, but cannot be used with flocculant cartridges. Here you should pay attention to the manufacturer's recommendation.
Facts worth knowing about flocculants
How much flocculant should I use?
The manufacturers' specifications vary greatly in some cases. With flocculant cartridges, you can use one cartridge a week for a pool with up to 50,000L of water.
For liquid flocculants, the range is from 10ml per 10,000L of water to 2L per 10,000L of water.
Therefore, pay particular attention to the manufacturer's dosing instructions.
Does the flocculant have to be removed from the pool after use?
No, the flocculant combines with the dirt particles, making them filterable. This means that the flocculant ends up in the filter system with the rest of the substances.
How environmentally friendly is flocculant?
Since the flocculant combines with other substances and is finally brought out of the pool in the filter system, there is generally no danger to the environment. Of course, only if used properly, because flocculants are biocides and thus not entirely harmless to humans.
If you would rather play it safe and use an environmentally friendly cleaning agent for your pool, you can always use vitamin C powder.
