My 3ft tank had sand in the bottom, left over from a tropical set up. When I removed the power filters I used two corner air driven filters that sat on the sand, which I though was good enough for the goldfish.
When I can to dismantle the tank to move it, I noticed the vibration from the filter had caused the sand to not only ware away the corner of the filter, but had also warn a grove in the tank. Luckily for me this was a well made tank with a very thick glass base. If this had been my old 3ft tank, it would have failed.
I don't use sand any more.
