All pools must periodically need to clean the bottom of.

The Pool cleaner current solution is: first add calcium hypochlorite, the filter bypass (that is, only cycle, no filter), the purpose of the calcium hypochlorite fully mixed evenly, two hours later, turn off the filter, settling for 24 hours. After 24 hours, the reopening of filtration (filter state), with a long tube inserted into swimming pool cleaner, a bottom carpet along the road, this time, the bottom of the brown sludge and sediment disinfection will be sucked into the filter device and is filtered out. Because you did not say that is the end of your pool water or edge of the water, so I do not know if you should end when the suction tube is inserted in one end of the pool or the bottom. Or, in the overflow tank outlet, you can also look at the diameter size, with a diameter hose right, so do not pick up a tube of water. Hose and the other end tied to the root of a long-handled, standing beside the pool like the operation. After absorbing all the best day at the end, so that the dirt will not end up with the plot.
