"Simple as possible"? BB baby!~~

Seriously, sounds like fun. I've never had a nano before but have been very tempted to set one up... one of my LFS has a 12 gal nano that is just A-dorable!!! I hear the upkeep on them is surprisingly high though

You have a great idea using yours for a QT tank!! Keep us posted and, as always, share the PICS when you get them!!!
