Great looking tank, you've really put a lot of time and energy into it. All of these pictures I've been seeing of everyones tanks gets me really excited, I can't wait to start my tank this weekend.
During the winter here I could pull it off with a couple tank heaters. My sister lives in Austin, and it was only warmer there 15 days out of the last 50.
7 month old labs are more work than 2 reef tanks, they also make bigger messes.
