Well Navarre..on the lighter side, I credit your wife with her patience for your aquaristic pursuits. And...I thought 20 lbs of nano rock was expensive. LOL.I finally got to read thru this post and I give you credit for maintaining your patience and persistence thru those difficult tank times. When you have time, try and finish up your diagram with Sketch Up when you have the final layout of your plumbing for this tank. Kudos. SH
