Now that the water is circulating properly, good filtration removes dirt, debris & even certain large bacteria & algae. Sand filters remove the largest particles, Cartridge filters remove smaller particles & DE filters remove the smallest. Filter your water for 8 to 12 hours every day from opening to closing. Use a timer so that you don't forget and save money. By the way, for the best filtration, be sure to chemically clean your filter about twice each season to remove accumulations of greases, oils & other swimmer and environmental waste that clog your pool filter & that routine backwashing & rinsing will NOT remove.
The first four items are considered a must and should be kept on hand at all times. The following suggestions are optional items which are nice to have available but not best pool cleaner always needed.
Purchasing a pool can be a scary experience, especially for those first timers who haven't been through the process.

Clean and dry the cover then store it in a dry location.
Another cleaner is the Robotic pool cleaner. With the help of advance technology, these cleaners were designed to help many swimming pool owners to effectively clean their pools. This cleaner works independently with the use of electric motor found inside the product. All the user needs to do is to plug the cleaner in an outlet, put the cleaner into the pool and turn it on during the time of cleaning. They are the best choice when it comes to small debris or fine sand. Among the three types, this is the only cleaner that scrubs not only the floor and walls, but also the lines of the tiles. Some robotic cleaners have a remote control to allow you to guide it clean the areas which may have missed. Though this type of cleaner is a bit expensive, ranging from $500-$2000, it's a very good investment.
