The Pool Experts / How does a pool work? - THE COOL POOL by Astralpool Australia

At first sight, a pool does not look that complicated. After all, it is a big hole in the ground full of water. However, there are various parts hidden under the surface that fit together to form its sophisticated inner workings, which enable us to have a great time splashing around in crystal clear water. Your pool is one of the largest and most important investments you will ever make. It is important that it looks great, is healthy and safe to swim in and continues to add value to your house at all times.

Pool water moves in a continuous cycle, whose centrepiece is the pump. Equipped with an electric motor, this device has an impeller that drives water through the skimmers and sumps (found at the top and bottom of a pool, respectively), takes it to the filter and then returns it clean through the return nozzles, a series of small valves placed around the pool. AstralPool has introduced the Viron XT variable-speed pump range. The pumps have nine-start energy efficiency, fast and overdrive functionality making it the efficient solution for a filtration pump for your pool.

To prevent a pump from becoming clogged up, the water goes through a basket-type plastic pre filter in order to retain leaves and other debris that is sufficiently big to block the mechanism before it reaches the pump. From the pump, the water reaches the filtration system, where any small particles of dirt are held back.

Plastic filters tanks that contain a filter bed, made of sand or glass. Gravity pushes the water through the sand or glass, which trap any dirt. When the water passes through the filter medium, it is pumped to the outlet pipe, which returns it to the pool. Obviously, as time goes by the filter medium must be cleaned, as the dirt that has built up can slow down the flow of water.

The core needs of any swimming pool are the filtration system which removes unsightly organic matter that feeds bacteria and algae plus the sanitiser which destroys any algae and bacteria which enters the water. Modern-day pumps, filters and pool cleaners remove the organic matter very effectively and automatically, almost eliminating day to day maintenance. Chlorinators cleverly produce sufficient sanitiser to destroy bacteria and algae but almost none regulate the amount of sanitiser or adjust the water balance, making it one of the most popular and healthy products on the market to ensure your pool is safe, healthy and looking great.

These are the basic components involved in how a pool works. However, there are other devices that although seemingly inconsequential are able to streamline a pool’s performance and turn it into an oasis of well-being:

Robotic Pool Cleaners go over the pool floor and ensure a thorough clean of the shell, as well as consuming very little water.

Heating systems make it possible to keep that water at a certain temperature and should be fitted with the filtration system and dispenser. AstralPool provides two options to extend your swimming season and swim comfortably all year round – gas heaters and inverter heater pumps.

SLX multi-colour LED Pool and Spa lights keep power consumption down to a minimum, whilst the light that shines from the walls creates a relaxing atmosphere worthy of any great design.
