I also just recently purchased a 34 gallon Red Sea Max and switched everything over from my 29 gallon. I am having difficulty accessing the carbon/filter media, however. Surely, you can change this material...any ideas? By the way, how are you liking the protein skimmer? Mine hasn't been producing much of anything, that I've noticed...and excuse the quality of the picture, it was taken with my phone. Other than that, I am looking forward to the extra space for corals....
