So I'm off to the LFS today. I've decided to get some aragonite for buffering. I considered the peppered eco-complete cichlid substrate, but when I think of it, most of lake TK is white sand. I've seen shots of peppered too, but for all my research and photos, never seen pure black sand. I figured it would be easier to pepper the sand or cover it in rock rather than trying to introduce a new substrate later if I've messed up. After this and a heavy cleaning of the 10g, it's back to the documentary n' crap.
Also of note, is that I was talking to my father last night on skype. He did a little research of his own for me, and found this link:

I haven't looked at it outside of scanning a couple journals, but there's a huge pile of info in them. Most of the papers seem to be 100+ pages long. The focus is more from sustainable fisheries than anything, but there's an ecological concern to the thing. I'm hoping it'll turn up some good stuff.
