For a pool owner, a healthy pool is a tall order. Filters and cleaners must work round-the-clock to get rid of contaminants from the environment, as well as those that swimmers may leave behind. This is one reason why swimmers are required to shower before going into a public pool. It lessens the burden on Perth pool filters and cleaning agents.
Even in your own backyard pool, a quick shower before swimming is a good idea. Studies show that the average swimmer carries 0.14 grams of faecal matter that can get into the water if the person does not shower first. If this is not alarming enough, the same studies also found that the human skin holds more contaminants that are just waiting to be washed away.
