How to change your pool filter sand


When was the last time you changed the sand in your pool filter? Your pool filter sand is one of those things that only gets changed every so often. Usually, every 3 to 4 years; because of this, it can be easy to forget.

Clean sand in your pool filter is a very important part of keeping your pool water at its cleanest. As time goes by, your filter can become clogged with grime and debris. This build up makes your filter equipment work harder, costing you extra electricity and wear on your pool filtration system.

How do I know if my filter sand is dirty?

Old or dirty sand in your filter can make it harder to maintain water at proper levels, and often results in murky or cloudy water and can even make people sick. That being said sand is an excellent choice of filtration and is even used in many drinking water filtration systems. Additionally, sand is also eco-friendly and inexpensive.

IMPORTANT! Always use proper swimming pool filtration sand. Using the wrong type of sand can destroy your filter cartridge.
