Do you want your pool water to be of optimal quality all summer long? Want to know how to properly maintain your filter to get there? You\u2019re in the right place!
\r\nPool filters work thanks to different filtration media<\/a>, like sand <\/a>and glass<\/a>. To maximize the life of your filter and the quality of your water, you must use the right medium and replace it at the right frequency.\u00a0<\/p>\r\n

Our experts have tackled the matter to answer all your questions!<\/p>\r\n

Why is filtration sand so important?<\/h2>\r\n

To the naked eye, the sand you put in a pool filter may appear fairly uniform. However, each grain of sand has a rough texture that allows it to retain fine particles that wander into your pool water. This is how the sand purifies the water and prevents any contaminants from getting through.<\/p>\r\n

Why change the sand in your pool filter?<\/h3>\r\n

Filtration sand captures impurities present in the water, but over time it loses its effectiveness for different reasons:<\/p>\r\n

Debris Accumulation<\/strong>: Captured particles and debris eventually clog the sand and reduce its effectiveness.<\/p>\r\n

Natural wear<\/strong>: Over the years, the back and forth movement of water over the sand makes it smoother and smoother, and therefore less and less effective at trapping all those little unwanted particles.\u00a0<\/p>\r\n

Bacteria Growth<\/strong>: Bacteria can build up and create microorganisms that affect water quality.<\/p>\r\n

In short, if you never change the sand in your pool filter and it can no longer do its job properly, water quality will be greatly reduced (growth of algae, presence of bacteria, etc.).\u00a0<\/p>\r\n

Lime scale: a common problem in sand filters<\/h2>\r\n

With time, a small amount of limestone clings to the sand grains and accumulates. This causes the sand grains to clump together and become hard and compact.\u00a0<\/p>\r\n

These sand \u201cclusters\u201d affect filtration quality. In the worst-case scenario, all of the sand in the filter can become one big petrified block and not be effective at all. Regular backwashing and maintenance of the filter and sand with specially designed products are usually sufficient to avoid these problems.\u00a0<\/p>\r\n

When should you change the filtration sand?<\/h2>\r\n

No matter what type of sand you use, it must be changed to keep the filter working properly to remove contaminants from pool water.\u00a0<\/p>\r\n

In general, it is recommended to replace sand every 3 to 5 years.\u00a0 However, several signs may indicate the need for sooner change:<\/p>\r\n
