does anyone add sand their tank?

[PeeJ]

seems i filter some of my sand out...guess it gets blown around and sucked outward. do any of you add sand to your tanks every so often?

or is this a bad thing to do?

Put a little rubble or crushed coral over the top of your sand and this will help keep the sand on the bottom.

i made a "stone henge" out of rubble. seemed to help a bit.
