Cleaning the pool, how to remove dirt

Things that are cared for last longer - it may be a cliché and everyone knows it, but every item requires different maintenance. While with everyday items such as shoes, clothes or glasses, everyone knows how to clean and maintain them, it can be a problem with others. After all, not everyone is a gardener and not everyone knows how to look after a garden. Likewise with swimming pools, they too require specialised care. We'll teach you how to look after your pool after the season, before the season and how to combat algae and cloudy water.

  • The outdoor swimming pool should be prepared for wintering
  • It is a good idea to clean frame and inflatable pools according to the manufacturer's instructions.
  • Chemicals are the basis of pool cleanliness, there are formulations for different types of dirt
  • The basis of pool care is systematic and conscientious chemical and mechanical cleaning

Cleaning the pool after the season

When the summer is over and the temperature outside doesn't allow you to take a dip, you need to prepare for the winter and clean the pool after the season. A pool that is left to its own devices will cause a lot of problems when it comes to preparing it for the season, and may even make it impossible. Poorly prepared parts can get damaged, and this can cost us dearly. This is why you should start by draining your pool of water ...
... but not completely.

Step 1 - Lowering the water level

The first step when preparing the pool for the end of the season is to lower the water to a suitable level. It is accepted that the water line should be about 20 cm lower than the inflow jets. Water in sub-zero temperatures freezes and increases in volume. Therefore, the water level must be lowered so that the water does not burst the elements.

Step 2 - Dismantling and cleaning

It is also important to dismantle all the necessary pool equipment, which can be damaged by low temperatures. Water should be drained from the filter, circulation pump and heat pump so that residue does not damage the equipment. The pool basin should be cleaned of all dirt to slow down the growth of micro-organisms.

Step 3 - Pool chemistry

The final step is to apply pool chemistry. First we regulate the pH of the water, then we top up with a winter treatment and possibly cover the pool.

Cleaning the pool after winter

Several months without filtration, water movement and use of monthly measures. We can imagine what might have happened to the tank. However, it is getting warmer outside and one would like to enjoy relaxing in the water already. So how do you clean your pool after the winter?

Step 1 - Cleaning

The reverse process as for preparing for winterisation. Start by cleaning visible dirt. Use a brush and a net to fish out the dirt on the surface. A lot of tarnish and other deposits may have accumulated over the winter. If you haven't covered the pool, there are bound to be leaves and other 'debris' that may have got in there with the wind.

Step 2 - Installation of equipment

The next step will be to connect the appliances that have been tucked away for the winter to the system. The circulation pump, heat pump and filters can return to their place when the temperatures are higher outside the window. Once this step is done, we can top up the water to the appropriate level and turn on the equipment to start the filtration and water circulation process.

Step 3 - Adjusting the water parameters

The final step will be to adjust the water parameters. When starting up the pool, it is a good idea to carry out shock chlorination to get rid of any micro-organisms from the 'old water' and clean the 'new' water.

How to clean a garden pool

The above tips and information apply to professional outdoor pools, which require special care as they do not "hide" like garden inflatable and frame pools. Therefore, clean your garden pool in this way:

Step 1 - Drain the water

In order to clean the pool thoroughly, it is best to drain the water completely. Don't let the miser in you speak. The water bill, will be much less than the cost of a new pool when this one gets damaged. You can use the water to water your flowers, but wait until the chlorine in the water has completely oxidised to avoid damaging your beds.

Step 2 - Cleaning the basin

After emptying the water, the inside of the pool should be thoroughly cleaned of any sediment, dirt and deposits that have formed during use. Only then should the pool be stored in a dry, warm place. Failure to do this can lead to bacterial growth and the formation of mould. In some cases, water and cleaning fluid may not be enough. There are special pool cleaners available. For delicate pool parts, it is a good idea to use soft sponges and cloths.

It is worth taking a look at the user manual provided by the pool manufacturer. A lot of valuable information on cleaning and maintenance appears there. Manufacturers indicate which chemicals are safe and which should be avoided. A well-maintained garden pool will last for years.

How to clean a swimming pool of sediment and scale

Water has many minerals in it. Their precipitation and deposition is a natural process. Dirt is so persistent that it clings to its surface very well. Anyone who has had the opportunity to clean their shower cubicle and bathroom fittings knows this. Fortunately, there are special preparations that make it easy to clean the surface of the pool of limescale and lime deposits.

Some of these are very strong and contain hydrochloric acid, so read the leaflet for information on the use of such a preparation before use. Regardless of the formulation, it is applied in the same way. An appropriate amount is applied to the surface. Depending on the manufacturer, several minutes are allowed. During this time, the product dissolves scale and deposits. Finally, the surface is cleaned with a brush and rinsed with water.

Cleaning the pool when the water becomes cloudy

Cloudy and milky coloured pool water is a sight that no one wants to see. Fortunately, the problem is widespread and very familiar, and this means that cleaning the pool when the water becomes cloudy is not secret knowledge. The milky colour occurs when there is fine suspended dirt floating in it. There can be two reasons for this.

Cause 1 - Soiling too fine

Turbidity occurs when the coagulation agent is not used. Some of the impurities floating in the water are too fine to be caught by the filtration system. Therefore, a physical process called coagulation is required. This is done with a special preparation that breaks up fine particles of pollutants into larger clusters that the filter is able to retain. The water should then become clear.

Cause 2 - Too much chemistry

The second cause may be too much chemical. Stop dosing this amount of preparations and clean the water according to the standard procedure. Manually clean the basin, measure the pH of the water, adjust it to 7-7.4, apply flocculant and filter the water. In this situation it is also worth cleaning the filter, which may also be dirty.

Cleaning the pool of sand

Sand in water is one of the types of dirt that is very easy to clean. Its particles are so large that filtration can handle it without any problems. Using a pool cleaner will also be effective. There are manual and automatic vacuum cleaners on the market. Both types will cope with this kind of dirt at an express pace.

How to clean a swimming pool of algae

Algae in the pool manifests itself as a green colouring of the water. This is enough to effectively discourage swimming. This happens when the pool owner's responsibilities are neglected and the care of the water and pool basin is inadequate. The appearance of algae in the pool means that there is a bit of work ahead in terms of restoring cleanliness.

First of all, you should start by cleaning the filter and carrying out shock chlorination. This involves exceeding the normal chlorine dose several times. Special preparations are used for this. At the end of the whole procedure, a "mechanical" cleaning of the pool basin awaits us. This can be done with brushes and a pool hoover. In addition to green water, an additional symptom of algae in the pool is a slippery residue on the bottom and walls of the pool. Mechanical cleaning will get rid of the residue.

Not just pleasures, but responsibilities

The water in a swimming pool needs special care if it is to be pristine. It's not made any easier by people swimming in it, but that's what a pool is for. So it needs to be cleaned regularly with chemicals and brushes. This is the only way to ensure long and safe fun. The procedure itself is not difficult and requires no specialist skills. The key to success is regularity and diligence. In water, reactions happen very quickly and unfortunately it is not always possible to "wait".

Do I have to clean the outdoor pool after the season?

In theory, you don't have to and you can only clean the pool in spring, but it is worth doing. It will make your job easier when you open the pool. Don't forget the winterising agent, though.

How to deal with greasy deposits

There are special products for cleaning this type of dirt. We recommend Bordnet Spray or HTH Waterline Cleaner.

Whether to cover the pool before winter

If you have a special winter cover then yes, it is worth covering the pool. However, it must not be an ordinary solar film that will sink under the weight of, for example, snow.

Water turned brown after chlorine was added

If the water has turned brown soon after adding chlorine and the walls are not slippery, this means that there is a lot of iron in the water. Use Metal Magic to precipitate the iron out of the water.
