Welcome to the forum, and welcome back to the adventure of reefing! Try to remember that the most expensive thing in reefing is impatience. Also stability is key, if you have to make changes in parameters or even lighting make them slowly over time. These are just a couple things that I have learned from reading posts from the people on this forum with far more experience than I have. I am also a new member here who has been reading posts for a while before joining. I have been impressed by people on this forums friendliness and willingness to help others enjoy this hobby. I hope you keep us updated with the progress of your new tank.
