Sand or bare, {corals}

[Dyspnea]

I've had bare bottom, sand 3-4 inches and some .5-1 inch sand bed and even crushed coral.

Bare bottom was nice for keeping debris build up low, but I have always enjoyed having a bit of sand.

I never believed or bought into the hype of dsb's, but 1-2 inches of sand is a sweet spot, and it's easy enough too suction clean.
