Maintenance of sand tanks in swimming pools Equipped with sand tanks in swimming pools can help water treatment, but if you do not pay attention to maintenance, it will reduce the filtering effect of the sand tanks and affect its service life. Generally, you need to install the following three methods to do it. 1. Backwashing is generally carried out 2-3 times a month, and the backwashing time is generally 5-10 minutes. (For example, once a week in peak seasons) 2. Sand tank cleaning is generally done after the swimming season ends or before the opening of the second year. It is best to carry out a cleaning to avoid the oil produced by the human body accumulating in the sand for a long time, which will cause the sand to agglomerate and affect the filtering effect. You can use clean water and sand cleaning agent to clean the sand tank. 3. Sand replacement Generally, after three years of use, the sand tank needs to be replaced with quartz sand.
Because quartz sand will become smaller due to friction after long-term use, and part of it will be washed away after backwashing. If it is not replaced for a long time, fine sand particles will rush into the swimming pool with the water flow after normal circulation, affecting water quality. .
