Well I started by reading articles in about.com
Then I found reefcentral that has some informationa and a forum.
And then I found this forum, where I spend most of my time reading other people's topic.
See how they setup their tank, sump, refugium, etc.
I've been reading articles and posts for about 9 months and to be honest, all I know is about setting up the aquarium.
Nothing about fish compatibility, eating habits, corals or invertebrates.
So if you want to start in a month, you'll probably have to study more than you did in highschool!
