Crystal clear pool water - how to achieve it

The dream of every pool owner, whether it's an indoor, outdoor, frame or inflatable pool, is crystal clear water. You just want to jump in. With very small pools, the water can be changed frequently and you won't feel it in your bills. However, constantly replacing it in a 20 m2 pool can be hard on the household budget. Fortunately, there are ways to keep the water crystal clear, and this will allow you to enjoy swimming for a long time.

  • Filtration is one of the three basic elements in maintaining clean water
  • The use of chemicals is an effective complement to filtration, without measures the water will be dirty
  • The pool basin should be cleaned mechanically with hoovers and brushes.
  • Without the use of chemicals, it is impossible to maintain a clean pool

Crystal and azure water - is it possible?

In photographs from exclusive hotels or opulent villas, we see that the pool water is in impeccable condition and a beautiful azure colour. Living in the world of social media, we assume in advance that this is surely the effect of filters from 'instagram'. It turns out that this is not necessarily the case and this effect is achievable. You too can have crystal clear water in your pool. However, it will require you to be systematic, meticulous and thorough.

We must admit that the colour of the water is a delicate trick. As you know, the water itself is colourless and the 'azure' effect is very dependent on the basin. When planning your pool, it is worth asking your designer which finish colour will give the desired effect. From experience, we know that white and light blue basins, most resemble azure shores. If you look closely, most cheap inflatable pools have just this colour to enhance the visual effect of the water.

3 ingredients for success

Crystal-clear water is only achievable if it fulfils three basic points, which are a primer for any pool owner.

A pool pump connected to a sand filter is an essential component for enjoying clean water for a long time. Without this kit, we won't be able to keep the pool water in impeccable condition. The pump must have the right capacity to do its job. It is assumed that a well-chosen pool filter pump should be able to pump all the water inside the pool four times in 24 hours. The pump should have a 'reserve' of power to make it more efficient. A pump that is too weak will be worse at removing contaminants from our pool.

The pump should be connected to a sand filter, this is what will clean the water. Sand is ideal for retaining all impurities. It can be replaced by another filter bed, such as filter glass or diatomaceous earth. The filter must also be chosen to suit the size of the pool. Too small will make filtration ineffective and too large will choke the pump.

The filter pump should run a MINIMUM of 8 hours per day, but we recommend extending the filtration time.

Filtration alone is not enough to keep the pool water perfectly clean. It needs to be disinfected regularly. The water - in which people bathe and various pollutants fall into it - is an ideal environment for the growth of micro-organisms, so disinfection is essential. The best method is chlorination. We recommend the use of multifunctional tablets, which contain multiple agents. These include, among others, chlorine, a pH regulator, an algaecide and a crystalliser. Its regular use guarantees clean pool water. Application is very simple, drop the correct amount recommended by the manufacturer into the dosing buoy or skimmer.

Some of the impurities in the water are very fine, the water becomes cloudy and the filtration cannot catch everything. There is also a solution for this. In addition to chlorination, coagulants should be used. These are special preparations that clump fine dirt into larger clusters. This makes it much easier for the sand filter to catch them and the water is crystal clear. The agent should be used in accordance with the manufacturer's recommendations.

Remember to check the pH level of the water before applying any pool chemical. It must be between 7 and 7.4, otherwise the preparations will be ineffective. The pH value should be checked regularly, only the ideal parameters will keep it clean.

For the perfect complement to filtration and the use of good-quality swimming pool chemicals. We have to add a mechanical cleaning of the basin. Not everything is captured by filtration. Floating leaves should be caught with a net. On the walls of the basin and on the bottom, there may be tarnish and sticky sediment. It should be cleaned with a brush. Pay particular attention to the water line. It is there that the most greasy sediments are deposited, which the swimmers in the pool bring with them. Usually these are leftover cosmetics and dirt from the body. There are special preparations and sponges to help clean the water line.

It is worth considering buying a manual or automatic pool vacuum cleaner. These are devices that facilitate and accelerate the cleaning of the pool. Moreover, they are much more accurate. Its principle of operation is identical to the classic version of the vacuum cleaner. However, this one also sucks water into the pool. Dirt is trapped in the filter and the purified water flows back into the pool. A vacuum cleaner is useful when the pool has a large area. We cannot forget one important rule. The unused pool is a covered pool. Solar foil or roller shutter not only keeps the water warm, but also protects against external contamination. Leaves, bird droppings, dust, etc. may fall into the pool water. The foil protects the tank and marginalizes the possibility of such contamination

Clean pool water without chemicals

In recent years, 'chemistry' has had a very negative connotation. We associate this word with something artificial, harmful, dangerous to health. We then resort to natural means. A trend that is particularly evident in the cosmetics industry. This is where natural ingredients add value.

Unfortunately, in the case of a swimming pool, it is impossible to keep the water crystal clear without using chemicals. On the internet, you can find many supposedly 'proven' ideas. Among them is the popular one of pouring in vitamin C. This method may have a visual effect, but it is short-lived and can do a lot of damage. Vitamin C is very acidifying to water, and this has a negative impact on our skin.

We guarantee that high-quality pool chemicals are completely safe. Of course, if you use them according to the manufacturer's recommendations. Using the right chemicals will ensure that the water in our pool is crystal clear.

Does the size of the filter need to fit the pool?

Yes, the size of the filter is on the capacity of the pump and this on the size of the pool. So choosing the right filter is very important. Water that is too small can burst, and water that is too large will 'smother' it.

What happens if the filtration goes less than 8 hours?

If the filtration time is too short, algae will develop in the water, the water will become cloudy due to sediment, It will require more work from us to restore the pool to its ideal condition.

Does the pool have to have a blue basin to make the water look good?

The colour of the basin is a matter of taste. There are some people who choose black basins when building a pool. If the water is crystal clear, it will look good in any colour of basin.

Is the use of multifunctional tablets alone sufficient?

As a rule, yes, but it depends on the 'conditions'. It may be that the concentration of other agents is too low and you need to support it with additional agents. Not forgetting, of course, filtration and mechanical cleaning.
