Do not be enticed by the lower prices of the prefabricated pools in the big retail chains.

The problems begin as soon as the installation of the pool. Even a light wind is enough to complicate significantly the positioning of the metal construction on the bottom rail. By placing the liner if it is not well-fixed to the top of the structure, then during the filling of the pool with water is very likely the entire structure to be destroyed. In this case, if the equipment  "survives" you should start all over again.

Another disadvantage of these pools is the low circulation of water. In this case, water becomes unusable for swimming because of the emergence of microorganisms bearing diseases. Even the shock treatment with chlorine is unable to help because it can't be spread all over the pool, because of low water circulation.

Also from the filter pump has a lot to be desired. With the pollution of the filter its power reduces significantly. Furthermore, on the instructions is indicated that the pump should be switched off when there are people in the pool for security reasons which additionally worsens the circulation of the water in the pool.

The pools are equipped with a cartridge filter, which are not sufficient from the viewpoint of hygiene in the pool. Cartridge filters have two major disadvantages: do not allow understanding to what extent are polluted; the possibilities for cleaning of the filter are limited. According to the manufacturers the filter should be washed and cleaned with a brush. But washing can not remove the pollutants in the folds, and the cleaning brush is likely to damage the filter carton.
Therefore, it would be reasonable to obtain a sand filter with pump. Sand filters are cleaned by backwash which regulates the need for fresh water in the pool. If you want clear water you will not get away only with this additional cost.

Because of the low circulation of the water on the bottom of the pool gather pollutants and they can be removed only by the manual cleaner. Neither of these pools is offered with a cleaner and the pump can not connect to the cleaner which means more costs.

The prefabricated pools of high quality have the following qualities:

• The steel construction is 0,6mm or 0,8mm thick, galvanized, with additional cover outside
• The liner is 0,6mm thick- 3 times stronger than the liner of the cheaper pools
• The ladder is stable and is made of stainless steel
• The sand filter has enough strength to sucks the pollutants on the bottom and is able to maintain the water clear
• The skimmer is installed in the pool and doesn’t impede to the swimming.
• There are no electric devices put directly on the construction.
