the one thing i like about a thin sand bed, is the notion that if it looks dirty, you can siphon it out, clean it and put it back, or just replace the thin covering, and then the tank would look all purdy again! ofcourse providing the tank has sufficient biological filtration to sustain the tank, without causing any spikes when the sanded is removed.
just a thought.
