Pretty much all my thoughts lately have been around reefing. Even once I get my 12 gal where I want it exactly, I'm already thinking of the next build, and where in the house my nicely established tank would go. It's amazing how long it takes to really learn in this hobby. I've been on and off for 6 years, and feel I am just getting there (in terms of setting up and working with problems with my experience). I feel it takes an amazing amount of failure to learn how to make the correct choices, have that be husbandry, chemistry, equipment, or livestock selection. I love it!
