I removed sand a few months ago and totally love it. The bottom is now totally covered with coraline and the Kole Tang keep it free of algae/diatom. It's personal preference aesthetically but it's definitely easier to maintain. Only thing is not able to keep some of the sand dwelling fish.
Same here only took acouple weeks and my bottom glass has coraline all over the place. There was a couple thing that I was thinking of getting that need sand but that's ok because I much rather have BB maybe I just need another tank
