D Azur blue, it can seem as though you re paying a lot of dough for not very much. Swimming pools are actually very complex beasts, balanced in a delicate state of equilibrium. And there are three key processes chlorination, filtration and circulation which go hand in hand to keep the water crystal clear.
Chlorine makes sure that nothing can live in the water.
Filtration takes the muck and leaves out of the pool. Circulation makes sure that all the water in the pool gets to go through the filtration system on a regular basis. If even one of them isn t working properly then the whole system gets out of balance, and the pool will very quickly turn a nasty shade of olive. There s a whole array of things which can cause a swimming pool to stop working properly. Do top up if the water level falls below the skimmers then your pump will suck air, and could burn out.
