Vacuum Gravel During Water Change?

[anzio]

Just wonder how many hobbyists here vacuum the dirt from the gravel during water change or just leave those dirt alone. Is it necessary to remove those dirt once a while?

I do. Just the stuff that's sitting on the surface. And only when it gets obvious or after a major uprooting and replanting.

i do siphon the dirt trapped on the gravel surface

Thank you for the replies. Oh ya, "siphon" is the correct word. Guess I would feel more comfortable too siphoning surface dirt when changing water. cheers....
