I'll start by stating upfront that I do not have a green thumb. I've taken plant prop and horticulture classes. I know a decent amount of the chemical and technical processes, but am absolutely terrible at keeping the dang things alive. I bought some Anachris and some Hornwort a few weeks ago. Half of the Hornwort is doing okay and half of it has its needles flared out and is looking like it's about to go brown. It's floating, not anchored to anything. I tried turning it every once in a while because it was the stuff that wasn't exposed to light that started looking pathetic, but it's not really improving.
My Anachris is even worse off. I thought it was completely dead, the leaves are breaking apart and some are falling off. Then I noticed that I'm getting some happy-looking new growth popping out from the sides. It's making kind of a Y shape. I was wondering if it would be a good idea to cut off the branch of the Y that wasn't doing as well so more nutrients would get to the fresh growth. The plants got thrown around quite a bit when I was first putting the tank together, so I don't know if that's part of what has them looking so bad. On the Anachris, I cut off the very bottom of the stem (1/4-1/2") to see if I could get some roots to start about 10 days ago. Then I got to reading and it sounds like they're not supposed to root anyway. However, it was shortly after I cut the bottom off that the new growth started coming up. It's growing really nice, but the leaves that were dessicated aren't improving at all.
Does anyone have any suggestions for making these dang things survive? I'm a little worried that if I don't get the nearly-dead stuff out of there, it's going to start rotting and there won't be anything to absorb the ammonia.
