why do you believe you need to change the sand? my understanding was that you should basically never have to change out the sand.

If the pool is always cloudy, no matter how well the water is balanced, it’s probably time for a sand change. Typically 3-5 years. Glass media lasts longer though, and filters better.

You think the sand doesn’t move in the filter? Your question has already been answered in this thread. But you continue to laugh like you know lol

I must be lucky mine is older than 10 for sure.

Chat GPT to the rescue;
Pool filter sand usually needs to be changed about every 5–7 years for a typical residential pool.

You may need to replace it sooner if you notice:

* Cloudy water that won’t clear up
* Poor filtration even after backwashing
* Sand blowing into the pool
* Higher filter pressure
* Channeling (water cuts paths through hardened sand)

Over time, the sand grains become smoother and less effective at trapping debris.

A few general guidelines:

* Backwash when filter pressure rises about 8–10 psi over normal
* Deep clean the sand once or twice per season if possible
* Most filters use #20 silica sand

If you have a saltwater pool, heavy debris load, or year-round use, you may end up replacing it closer to the 3–5 year range.
