All my reading has been done on the web so far...dead trees are SO 90's
.
I just did a bit more reading on BB tanks, and I personally don't see the point. You lose the (supposed) denitrification abilities of the DSB, and I don't see any additional gain, besides easy clean up.
I'm personally of the mindset to keep it as natural as possible, and in my mind at least, a DSB comes closest to that. ... That being said, I'm more than open to anything anyone's willing to share. I haven't bought a single thing yet, so nothing's too late.
