I can't find the article I am thinking of, but there was an interview with Eric B about going skimmer-less and bare bottom. Was a good read regardless of opinion.
Personally I run bare bottom and skimmer-less in my
nano with MUCH success. I wouldn't recommend this what so ever for someone who cannot give their tank attention everyday. I'm sure many people out there would disagree with my setup; but I am successful with my tank and have only had one crash (due to hqi lighting and no uv shield, not water quality).
My point here is there isn't a right or wrong, there is pros and cons, but every tank is different; and ultimately, a tank's health is up to the keeper! Sand or no sand, take care of your tank and monitor it!
