I never got around to starting a thread. And I'm still getting used to working my way around the forum. I've got a very simple setup. I can converted a fresh water tank and currently have a hang on filter with filter floss, carbon, and poly filter. The rock is about 19 years old and came with me when we relocated to Cape Cod. The original tanks had been set up since 2003. The hobby has changed quite a bit since I was paying attention as I mostly just took care of my fish and coral until we had to move everything. Anyway I started getting serious again just shy of 2 years ago. So this is my 29 and eventually I will post about my 72 gallon once I figure out what to do with my purple dotty back that is preventing me from adding any other fish to the tank!
