Hereof, how full of sand should a pool filter be?
Sand filters are not filled completely full of sand, but only about 2/3 full, to allow “Freeboard” space in the tank, above the sand bed.
Secondly, how often should I change pool filter sand? How often should the sand in a swimming pool filter be changed? We recommend changing the sand every five years. While we have seen filters go 20 years or more without changing the sand and still do the job, they are not as efficient as they should be.
Just so, how much sand do I need for a 24 sand filter?

What happens if you put too much sand in a sand filter?
If you have too much sand, the sand bed will be above the point where the tank starts to taper. This means the filter will behave like a smaller filter, requiring more frequent backwashing and causing higher resistance to flow. If it was high enough, you could see sand making its way into the returns.
