IMO ... (key word)

I would go BB in a nano... as you'll see how quickly nitrates and phosphates can build up. When you think about it.. unless you have something that can really stir up the sand... its just like a bed of gunk and crap... a bed of gunk and crap that you can't really see.

Over time it just keeps building up, right? But in a BB tank, nothing can settle in the bottom like that... and keeping the tank free of detritus would be much easier IMO.

Yes, it probably will look a little weird in the beginning, but overall and in the end I think it would be worth it...

That's just my view on it now, and I am thinking of going BB myself,.... at the very least if you do decide to go with sand, I would do the FSB, or a very small sand bed... (easier to keep clean this way as well)

Good luck, let us know what you go with
