I have returned to bare. Can't keep substrate clean enough for my liking. Miss the sand look but like being able to rearranging the plants at will. It happens automatically as I push the driftwood around while vacuuming the glass bottom. I do it almost daily to get the crap out before it can break down. +/-5 gals a day. All the crap gets hidden under the wood so you don't ever see it. Works for me.
