Asmodeus, thanks I really appreciate the kind comment.
As for cost, with a few exceptions, I have the same equipment on this tank as I did on my 225g. I just purchased stuff I would use on the next tank (the 600g). Over 225g I had 5 400W.
I added 1 400W MH and a sequence pump. The tunzes I added over time. The rock I picked up during a vacation in Hawaii, so that saved a great deal. I just added some T5s ( a tek T5 retro kit)
This hobby is not cheap, not by any stretch, but I think its worth it....
A large tank has always been my dream.....
Paul.
