Subscribe to Coral Magazine. Seriously.
"Everyone should be reading Coral." That's what I thought to myself months ago, and mentally added that topic to my ongoing list of future videos. Each issue has a central theme by multiple authors. Go subscribe now (we're tracking the results with this URL): http://www.coralmagazine.com/melev/
It really is a great publication, and you will learn all sorts of excellent points in every issue. I pick up new tips and factoids myself, and I've been in the hobby a long time. So whether you are new or have been reefkeeping a while, you'll benefit for sure.
