Bb
I do and love it. My 37G cube has been up for a little over two years and I think the only downside is I can't have some fish who need sand to sleep. I think the lps I keep on the bottom like not having sand in their mouths. Another plus, it was very easy to move back to NY.
btw - for those who always come back with BB does not look 'natural', check out Saba off St. Maartin - some of the best diving I have ever done - they have no sand.
I will repost this pic and try to get a better one.
