Hi all! I've been out of the hobby for a minute. I'm coming back and wanted to learn about some changes to the hobby since the 2003 era when I first began my journey and did a lot of research. A few factors for me are a bit different this time around compared to before. The main one, I used to live in a desert with temps averaging 110º, now I'm in Central Illinois where temps have been in the negatives. Any feedback to reefs in this environment? Any breakthroughs in technology, or reef keeping that I should be aware of that may have drastically changed?
