Most of you probably know about this book, and some of you have even contributed to the book. I recognized some names in the "Contributing Editors", so my guess is that you guys are on here as well

For those of you who don't know the book, you should really buy a copy! It's very comprehensive and just about everything you need to know about loaches is in this book. It even got my girlfriend a little hooked on loaches, and she got more in to my idea of getting a proper loach-tank.
I'm planning out a 450L~ tank filled with clowns, yoyos, and kubotais as we speak. We also need more space for our angels who live in an adequately tall tank, we just don't meet the volume requirements (120L and I think they need about 250L). Do you think that they will be okay with the added circulation from an extra powerhead? We'll probably end up buying a bigger tank for them somewhere in the future, but housing them in the 450 until we can get a tank for the angels.
