Swimming Pool Maintenance

What is the appropriate period for pool maintenance?

Periodicity or maintenance regularity of a swimming pool depends a lot on the type of the swimming pool in question, whether a private or public swimming pool, its location, its size, and regularity of usage.

Private swimming pools of a regular size may require two visits in order to guarantee its quality and smooth functioning.

Public swimming pools require special attention due to their high usage and, for this reason, should be taken cared of on a daily basis, always following the indicated chemistry dosages.

Why do swimming pools turn green?

Swimming pools turn green due to high algae growth, poor water circulation and/or filtration, improper use, or maintenance of chemicals, insufficient cleaning or other environmental influences.

Algae do not cause disease, but their presence is not an invitation for a dive.

What is the reason behind the corrosion of the metallic accessories of swimming pools like stairs, waterfalls or grids?

Corrosion or oxidation of metallic swimming pool parts can be due to pH levels or due to reduced calcium hardness in swimming pool water. The solution is to increase the pH levels to a range of 7.2 - 7.6 or to augment calcium hardness with a “hardness enhancer”.

Why does my swimming pool form a foam on its surfaced when used frequently?

Foamed swimming pool water is the result of an accumulation of body oils, lotions, deodorants, and other cosmetics. In this scenario, we recommend using an anti-foam product so as to eliminate the foam present in the swimming pool water and suggest making use of the shower prior to entering the swimming pool.

When i open my eyes underwater, i feel a burning sensation and a skin irritation when i’m in the swimming pool. What should i do?

It is extremely important to maintain water balance and regular maintenance, in order to provide maximum comfort for its user. Should the above problems present themselves, the user should analyse water parameters and inform the technician to facilitate the diagnosis and the solution in the shortest time.

Usually, the aforementioned symptoms are attributed to excess chlorine when, in fact, these are due to a pH level imbalance or due to a low level of free chlorine.

What is an engine room?

The engine room is the heart of the swimming pool, where one can find both the physical and chemical treatment equipment such as the filter, the swimming pool pumps and sewage, the control panel, the cleaning equipment, and chemical products.

Types of coating

What is the difference between concrete and masonry swimming pools?

It is in the structural components that we will find the main differences. A concrete swimming pool consists of a combination between concrete and hardware, while masonry swimming pools rely on a simpler structure with beams and columns for the support, filled with cement.

What is the difference between the liner and the membrane?

Liner swimming pools tend to be cheaper and faster to install, with a limited thickness and shorter lifespan, while the membrane is a longer-lasting coating that does not rot, is much more resistant to usage and weather conditions, ultraviolet rays, and water treatment products.

What is the type of coating most used by PROACQUA Water Technology?

To this date, PWT has coated 95% of its swimming pools with membrane coating, with a preference for the RENOLIT ALKORPLAN brand. It is our coating of choice given its flexible, soft albeit robust membrane, the result of the most advanced technological developments in swimming pools, which is prepared to resist the wear and tear expected from the daily use of a swimming pool, even under a large influx of bathers on a continuous manner and aggressive chemical products.

What are the required conditions for installing the RENOLIT ALKORPLAN Membrane

In a swimming pool equipped with a membrane, its bottom and walls are only there for support, without waterproofing functionality. Therefore, it will be necessary to:

  • Avoid contact of the membrane with underground waters (water tables, water infiltrations, etc.);
  • A preventive treatment of the walls and swimming pool bottom with fungicide and bactericide products is also advisable, so as to prevent the formation and proliferation of these microorganisms in-between the swimming pool and the coating.

Otherwise, organic contamination could come into contact with the membrane, which over time will give formation to stains on the coating.

Water treatment system

Would you like to know more about the big blue filters?

Big Blue Filters are polypropylene systems used for water and general liquids filtration. Their differential is liquid filtration in a high flow state. They are resistant to most acids, alcohol, ammonia, oils, and other aggressive chemicals. They are used with a one filter element cartridge (the big blue filter model) with leakproof o-ring sealing.

What is the ideal place to install my water treatment system?

Most people are only careful about the water they drink and not with the water used for cooking, pet-caring, teeth brushing, dish and clothes washing, or showering, among others. Filtering the water you drink and offer to your family is just as important as filtering the water utilized for other uses. The water filter at the entrance of your home will provide security for all uses, all the while offering peace, health, and savings in the medium term.

What is the appropriate period of precautionary maintenance for the water treatment system?

Frequency or regularity of maintenance of a water treatment system relies on many factors, namely the number of filters, filter capacity, water quality, and existence of any complementary systems. However, we always recommend changing the cartridges on a quarterly basis. Regardless of whether your filter is presenting saturation characteristics, this deadline should be respected for safety reasons.

What is the U.V. Lamp replacement time-frame?

U.V. lamps generally have a life span of 10,000 hours which is roughly equivalent to one year and five days.

Is the water treatment system the same for all types of water?

No. Most water treatment systems are designed to treat freshwater. However, in situations where we find ourselves facing brackish water or with high salt content, it is necessary to use an Osmosis suitable for that purpose, so as to ensure the water is treated correctly.

What are the benefits of investing in a water treatment system?

There are several benefits in investing in WT systems, from the prevention of innumerable diseases contracted from water such as Hepatitis, Tuberculosis, or urinary infections to the reduction of the logistics involved when buying water several times. Furthermore, in the long run, it offers a lesser financial weight and is more environmentally friendly.
