On this page (unless this post ends up starting a new page) there is a picture of the 'fish room' behind the scenes. I have a couple questions about it.
What is the whiteboard or paneling on the glass that's notched around the returns and what is it's purpose? Is it just to provide a backdrop so you don't see through the tank? Is it insulation of sorts?
Also, what is the purpose of that tall tank on the left?
Can we get a brief explanation of the function of each of those tanks? Are they all hooked in series to the main display?
Thanks,
