Welcome to the family! You definitely came to the right place. I would start with @dbl's advice (one smart cookie). Do some research. Then when particular questions arise (and they will arise) ask away. Glad to have you on the team.
Glad you joined us! You will love it here. I had a 75 reef tank back in the 90's and I believe it is still to this day, my favorite tank. It is a perfect size to play with.
