Sand or Gravel?

[Elaina]

I always was under the impression you couldn't vacuum the sand, so I've never used it, but now I think I'm gonna have to try it!

You can vacuum it, you just have to hold the vacuum thingie a fair distance away from the sand so you get the debris sitting on top of it without pulling up the sand itself. Hope that made sense. :)

i use a bucket when i vaccum my sand . that way, if i do suck up any sand, its in the bucket and when i dump out the dirty water i just add the fresh water and put it and the sand back into the tank, very easy
