Ok, im pulling up some plants yesterday. I noticed what looked to be activated charcoal chunks in my gravel/flourite. Ok, so i pull some out and sure enough it is! im going to assume it is many years old. the particular gravel i used came from my sump from my 240gal pred tank. should i pick it out or not worry about it?
I wouldn't worry about it at all. "Old" activated carbon might not be a bad substrate, with its high ion exchange capability plant roots should like it a lot. I believe it's even added to some terrestrial substrates, for better aeration.

Just about any Hygro will do the trick. You may also look into buying some watersprite, water wisteria, Asian Ambulia, and Myriophylliums. They are all quick growers and will eat up some of those extra nitrates.
