It is not unusual to have issues with your pool, relating to the sand that makes the water unclean. The more you utilize the pool the more sand there gets, particularly if you don't utilize special swimsuit. If the swimming pool is exposed most of the time, it is encouraged to utilize a pool sand filter which will get rid of all the sand that it can.
Normally an otherwise clean swimming pool can look truly dirty if the water has sand in it, and specifically if the bottom of the swimming pool is filled with sand. It can be difficult to remove manually given that the water with the sand in it, cannot be picked up with standard pool cleaning devices. A pool sand filter does the job for you.
In a sand filter like this, there will be a vessel where the water is pumped. A pipe mechanism will lead the water on the top of a filter then let the water rain at a natural rate through the filter. By doing this it is going to be filtered more effectively - if it would be filtered with pressure, a part of the sand would get through and damage your pump and other water filters.
Under the filter there will be another vessel which is going to collect the filtered water and lead it forwards to possible other filtration or water ionizer, then to the pump and back to the pool for another round. These sand eliminators generally clean themselves, however at event you might have to clean it manually, by removing it from your pool.
