A properly maintained filter is the key to a clean swimming pool. Generally the sand needs to be replaced every 4-5 years, depending on use but you can dramatically extend this with the use of Filter Brite once or twice a year. If starting with a new media filter, we highly recommend putting glass media in it than sand. It will last the lifetime of the filter without replacing and glass retains 4 times smaller particles than sand. This means clearer and crystalline water and reduces the bacterial growth within the filter so less backwashing is required.

Here’s Craig showing you how to do a sand change.
