The water in your pool contains more than just some chlorine and a leaf or two! We mentioned Calcium and Magnesium earlier, but there is much more in your pool that we need to pull out to really make it clean! Algae, body oils, suntan lotion, salt, etc. are just a few and to get all of that out of the water we have to run your water through a complex series of pipes, tubes, vessels and chambers. We have to neutralize the chlorine, introduce an anti-scalant, and run the water through an ultraviolet light to make sure it is as pure as it can be! We dare anything nasty to remain in that water as it goes back to your pool!
