Add more sand?

So I just did a deep cleaning of my sand (for the first time) yesterday....omg it was gross, and I quit after an hour. I plan on doing it again this weekend.
Anywho, when I opened the sand filter I noticed that the sand is WELL below the "minimum" line on the standpipe (i think that's what it is called). I know I put the proper amount in when we first set the pool up. Is this just due to settling and not an issue or do I need to add more sand? We have not lost any sand.

Thanks in advance!!

For whatever reason it seems to be gone....I'd add sand up to that line. On most filters this translates to about 2/3 full of the filter body. The rest empty space is called "freeboard".
