Frankly, I haven't cleaned my sand in the past year. If you have enough flow through the tank, nothing will collect on or in the sand. I'm running an FX5 on a 75 gallon tank which is about 3/4 full on average. The bottom of the intake is about 3 inches above the top of the sand. I don't think there is any sand in my filter, however, I haven't cleaned it in the past year either, so I can't say for certain. In my defense though, I will say that the water quality is still excellent, although I am getting a little bit of green algae growth on grains of sand and the docks, but I don't think it looks bad, it contributes to the pond-like ecosystem and look of the tank.
