very interesting topic. My take, to answer the threadstarter's qn, of course its biased.. Why? Because the (reefing) community perceives SPS dominated tanks to be holy grail of reefing. Rightly so or not, its really up to individual's perception aint it?
Like a few mentioned above, for non sps lovers, pls dont be discouraged by it.. Ultimately, we're all in this hobby bcoz we appreciate the marine world and want a slice of it in our living room.
Just to share, imo, an absolute gem of a tank.. im sure its been shared before..
