Water in swimming pools needs maintenance. Still water builds algae and bacteria and can be extremely dangerous if not taken care of. To eliminate this problem, a sanitizer known as chlorine is used in pools to keep the water clean and sterilized. Through evolving technology, chlorine is found in many different forms.

How much you are willing to spend? One can distinguish between two types of swimming pools, namely, above ground swimming pools or below ground swimming pools. Above ground swimming pools are smaller pools and are generally used for recreational activities and for a quick way to cool off in the summer. Above ground swimming pools are made of either plastic or metal, the latter being the more expensive yet more durable one. Below ground swimming pools are usually made from either fiberglass or they are reinforced with concrete and lined with a special plaster. Fiberglass looks great but after a few years of wear and tear, the fiberglass may crack which can easily result in injuries. Swimming pools can be constructed indoors or outside and if one is willing to spend extra, they can even contain artificial heating for the winter months.
