Sand or bare, {corals}

[MitchM]

I've started out bare, but I have a favia that is now starting to grow onto the acrylic bottom, which I do not want. It will make it very difficult to move if I let it continue.
I'm probably going to start adding a few cups of well rinsed sand every now and then to give me maybe a 1/2" overall depth.

I liked the bare look better than I thought I would. Very easy to keep clean.
