Maintaining swimming pools is a tough task and those who have them they know it better. Any knowledge about how to clean the pools is not known by most of the people. The water gets stagnated and becomes contaminated with debris, algae, and even germs if regular cleaning of pools is not done.

Cleaning of your swimming pool should be done every fortnight. The filter used to clean the pool should also be maintained and replaced. Specified types of filters are used to clean your swimming pool.

There are various types of filters available for your swimming pool. They are Sand " the bulletproof filter, Cartridge " the economic low maintenance filter, and Diatomaceous Earth – the water polisher.

Sand filter is the most commonly and widely used filter. To make the filter more efficient one has to change the sand in the filter. Otherwise, the sand will wear out enough to allow dirt to penetrate so deep that normal back-washing doesn't clean it completely.

Removing the old sand is the first step towards changing your sand. Disconnect the plumbing attached to the valve of the filter. Start digging out the sand once you have opened the filter.

Rather than a shovel, a small plastic cup has to be used to dig out the sand. Care should be taken that you do not break the laterals of your underdrain while digging the sand out. They are very fragile and are easily broken.

After removing the sand, examining the laterals is the next step. You can remove them easily by unscrewing it. For any damage or breakage, check it thoroughly and if there is any damage, then replace it duly. A mixture of dilute acid and water should be used to rinse it to remove all dirt in it.

The tank should be rinsed thoroughly after replacing the laterals. keep on pouring water till the tank is half full. After that, start putting in the sand. After you have added the proper amount of sand, reassemble the filter tank and/or multiple port valve. Always call the plumber for your assistance in case you face any problem during this process.
