Very nice. I can't wait to see this come together. I'm particularly interested in the black flourite and the black river gravel concept.
I have a couple of large swords (1 amazon and 1 Kleiner Bar) in my 75 today. I also have a couple of Pleco's (recent additions) in there too. Much to my dismay, they are eating my Amazon's leaves to transparency

. They don't seem to like the Kleiner Bar as much. I mention this because I notice that you are planning to add some pleco's to this tank.
btw. My pleco's are the Temmicki (sp?) variety. I'm really iffy on the spelling of that. I have it written down at home. I will say this though, unlike a common pleco, they are extremely active and are doing a great job on cleaning up what algae I have.
