Sand bed maintenance in a nano?

[typezero]

My display is a little over 2 years old. I never vacuumed my sand bed ever. My trick is during a water change, stir up a little part of your sand bed, siphon as much of that dusty water out to do your water change. After that i dump twice as much kz coral snow into the tank than normal. Helps the skimmer catch all the small particles.
