In the last two posts I briefly touched on two of the three basics of swimming pool maintenance, chemistry and circulation. In this post I'm going to finish off the series by talking about the last basic, filtration.
Filtration is the physical process of water flowing through a substrate, in order to purify and filter out organic and non organic matter. Depending on your pool, your going to have a different type of filtration system or filter. There are three main types of filtration systems for swimming pools.
Sand, DE (Diatomaceous Earth) and cartridge.
Each of these has the ability to filter out and catch algae as it grows, or filter out dead algae once the chlorine in the pool kills it.
A common signs that you have bad filtration inside your swimming pool is cloudy or murky water. Another is poor circulation inside your pool. (Remember the last post?)
Each filter has its own quirks and difficulties, and each one filters down to a different micron level. Sand filters have shown to filter less efficiently, and DE filters usually do a great job!
I hope you have enjoyed this series on the basics of swimming pool maintenance, if you have any questions, or if your sick and tired of maintaining your swimming pool yourself, we'd love to hear from you! Sometimes it is worth exploring the option of hiring a professional swimming pool cleaner in your area!
