Simple, because nothing purifi es water like
chlorine. Wind, rain, dust, and people introduce
bacteria and algae into your pool, along with other
contaminants. When enough chlorine is added to
offset these unwanted introductions, your pool
is said to have a “chlorine residual.” This is what
sanitizes your pool continuously. While there
are many types of chlorine, they all have several
important things in common. First, it’s the most
cost effective way to sanitize your pool. In fact,
chlorine has been the product of choice for 100
years. It’s safe enough to sanitize drinking water,
and powerful enough in the right concentrations
to kill deadly bacteria, germs and viruses. Unlike
chlorine alternatives, chlorine oxidizes while it sanitizes—
keeping your pool crystal clear. Remember
to test your pool daily, and keep your chlorine level
within the 2.0 to 4.0 parts per million range.
