Maintaining your Spa

The chemicals used in spas or hot tubs are very similar to swimming pools. There are some differences. These differences are due to the higher temperatures that spas and hot tubs operate at, the very high bather load per unit of water and the small volume of water present.

Spas can go wrong much more quickly than swimming pools, if you leave your spa without any sanitiser in it for several days it will start o grow organisms in it very quickly. These organisms will not only be in the parts of the spa you can see but also in all the pipework. They will form a layer on the inside of the pipes known as biofilm. Biofilm allows all sorts of organisms to grow under its' protective layer. Once biofilm is established it is hard to get rid of it. The best thing then is to establish a routine so that it does not get established in the first place.
