If there is green water in the pool, it is not just a visual problem. This can also result in health risks. Simple measures and home remedies can help to clean the pool.

In a nutshell

  • green water can form very quickly
  • Cleaning is often time-consuming
  • Home remedies are only partially gentle
  • Filtering can prevent the problem
  • Prevention is often the best solution

Green water: causes

If green water occurs in the pool, algae are responsible. As a result, the swimming pool is not only visually unappealing. The floor and walls also become streaky and slimy. Among other things, this can lead to slipping when entering or exiting the pool. There are also other potential difficulties, such as:

  • Skin irritation and irritation
  • tipping of the water
  • unpleasant smell
  • complete algae

It is therefore crucial that the appropriate measures are taken. This should already be done when the pool is set up. As well as regular cleaning.

Regular testing

The pH value of the water is crucial for the formation or growth of algae. It is ideal if the values are between the following figures:

  • Alkalinity between 80 and 150 ppm
  • Chlorine content about 3 ppm
  • pH from 7.2 to 7.6

Notice: Appropriate test kits can be found in specialist shops. A water sample can also be given to a hardware store or a pet shop, for example, to check the water values.

Adjust pH

If the pH values are too acidic, appropriate home remedies such as soda or a pH-Plus agent can be used. If the values are too alkaline, it makes sense to use vinegar or citric acid.
In any case, further tests must be carried out continuously so that the correct area can be targeted and algae can be avoided.

Tip: One test per week with a corresponding test strip makes adjustment easy. Deviations are noticed early on and adjustments can be made gently.

Filter

One of the easiest ways to prevent it is to properly filter the pool water. Various factors are required for this. These include, for example:

  • Cover: One of the most important preventative measures is covering the pool. As a result, no contaminating substances can fall into the pool.
  • Capacity: You must select the filter appropriately. Otherwise the algae can spread and form a streaky coating. It is better if the model has more capacity than there are liters in the tank. This allows you to keep the running time of the device short.
  • UV light: The use of UV light in the pool filter causes the algae to die off. The investment is therefore worthwhile and can prevent the spread of unwanted growth in the long term.
  • Changing the filter elements: Regular replacement prevents clogging of the filter and can make the use of other agents unnecessary.

chlorine

Chlorine, for example in the form of tablets, can not only kill algae and thus prevent a green film. The agent is also suitable for removing other impurities.
The application is quick and easy. Chlorine is available in different forms. The most common are tablets, which are very easy to dose. However, it can also be used in liquid form. It should be noted that the recommended dose is not exceeded. Otherwise, irritation of the skin and mucous membranes may occur.
It is also important that if the water is already heavily covered with algae and very green, a so-called shock chlorination is carried out first. Although this measure is chemical and anything but gentle, it can be the last resort. Otherwise the water must be completely replaced and the pool cleaned.
There are corresponding products on the market that make shock chlorination very easy.

cover

Covering the pool is one of the most important preventive measures against contamination and green water. Because flying leaves and other impurities contribute to the nutrient content, which in turn can promote the growth of algae. Another advantage of a tarpaulin is that this solution is not chemical.

Tip: Experience has shown that a custom-fit cover is recommended. It also reduces the effort involved in cleaning, is inexpensive and easy to use.

nets

Leaves and other foreign objects that have been brought in contribute to the fact that the pH value of the water can deviate from the desired range. It is therefore of crucial importance to remove the dirt as soon as possible. A landing net is ideal for this. Because at least coarse dirt can be removed quickly and easily with little effort.
It should be noted that the net should be as fine-meshed as possible. Although this increases the resistance during use, the cleaning effect also increases.

cleaning

Brushes that can be used manually are also a possibility, as is an automatically working robot. You can also achieve a preventive effect by removing the coverings. A thorough cleaning of the walls and the floor or the liner should be carried out at least once a year when the pool is emptied. If the water is cloudy, the measure is required more frequently. The water can remain in the pool during this time, provided that the suspended matter can be removed from it afterwards.
Landing nets and a powerful filter are suitable for this, for example.

Notice: When choosing the relevant cleaning utensils, you should make sure that they do not damage the surface. It is therefore crucial not to use too much pressure and tools that are too rough. Green water in the pool can also be avoided more quickly if cleaning is carried out more frequently.

site selection

The placement has a significant impact on the maintenance effort. Places under trees or bushes carry the risk that a lot of leaves fall into the water. Other foreign objects and dirt can also be entered.
Open spaces that are not exposed to direct sunlight can also be suitable. The following factors are helpful:

  • if necessary, use a close-meshed net as a cover
  • do not choose places directly next to deciduous plants
  • avoid direct sunlight

Frequently Asked Questions

Will all pools turn green unless the water is chemically treated?

No, as long as the right measures are taken, the water will remain clear. A combination of cover, filter and, if necessary, chlorine is usually sufficient to make swimming a pleasure and to prevent cloudiness and discoloration.

Why is it useful to wash before swimming?

Even small pieces of earth, leaves or blades of grass can have a significant impact on the water values. Rinsing your feet can therefore ensure that the pool water stays clear for longer.

Why does the water turn green and cloudy despite the filter?

There could be several causes responsible for this. These include, for example, an insufficient capacity of the filter or a lack of cleaning. A problem arises especially when cleaning in hard-to-reach areas. Because creases and grooves are predestined for further spread. They should therefore be given special attention.
