Swimming pools must be kept clean and hygienic by using a pool vacuum which has the capacity to clean large tiled areas. They should be covered while they are not being used. With a pool cover in use extra dirt and leaves don’t fall in, and the pool stays cleaner for longer. The next requirement is that swimming pools need to have proper circulation and filtration system in place to replace the stale water with fresh water. The pool pump helps in the circulation of the water. Swimming pool vacuums are also needed to clean out dirt that enters the pool. These are available in manual and automatic models. Manual vacuums are much cheaper than automatic ones. Your pool vacuum should be used to clean the bottom and sides of the pool. Some pool cleaners do an excellent job in general in cleaning your pool, however many of these devices will not pick up fine dust or sand that sinks to the bottom. However, a pool vacuum has to be used no matter what the location may be. The pool filter pump (or more than one for large pools) will need to be serviced regularly. Here is a tip for you. A pool suction hose can be turned into a backwash hose by using a hose clamp. A pool vacuum system consists of a number of parts that fit together to make the system fully functional. The vacuum head is that part of the pool vacuum system that is similar to a vacuum cleaner. Some pool packages come complete with a maintenance kit that includes a pool vacuum, others do not. If you are buying you will need to carefully establish exactly what is included in the price, before you pay out your money. As we have said already, filters can’t remove silt from the bottom. However, once the swimmers move the water they raise the silt, and it can then be be filtered out and the problem will slowly get better. Good quality filters will have a pressure gauge to tell you when they’ve absorbed too much particulate. For instance, the new Hayward 4800 DE filter, has a system that is affected when the pressure rises to 10 PSI more than the pressure when the filter powder was changed. When that happens the water flow is being unduly restricted and it’s time to change your powder again. When pool filling, add a water purifying chemical to the water to get rid of the remaining cloudiness in the pool. Follow the manufacturers recommendations. Chlorine kills any bacteria that may be in your pool water and that is why it is so important. Shock your pool once a week in the summer. Chlorine is typically prepared in liquid, powder or tablet form (though some professionals use gaseous chlorine), and it can be added to the water anywhere in the cycle. Pool experts generally recommend adding it just after the filtering process, using a chemical feeder.
