What a gorgeous tank. Your "fresh water reef" concept is so natural looking and the whole scape undulates across the tank with great rhythm and proportion.
I've already "plagiarized" your lighting approach and now I see you have the acrylic lily pipes that I was eyeballing as well. I'm concerned about the delicacy of glass and I am intrigued by the surface skimming function of this style.
How does the skimmer portion of the return work so far? Can you see a difference from the intake that you used previously? Any scratches from cleaning (mebbe too soon to tell)?
If you had to identify, in one word, the reason why the human race has not achieved, and never will achieve, its full potential, that word would be "meetings." óDave Barry
