thanks shane!

The tonina and wallichii are in only for 2 weeks now. I *think* that the wallichii is doigg just fine. Yesterday I had to trim two stems that reached the surface!! (I never had to trim this plant before, they just looked ratty and then died). I don't expect much from the tonina. No ADA AS and a KH of 4-5. Probably very hard to get this working.
And about the balsamica. It was in a very ba condition when I put it in the tank. Maybe it is just recovering. time will tell.

Another thing that I wondered about: Would it be possible to have just a little cup (or something similar) filled with ADA AS where I can grow the tonina in? In this way the tonina gets its ferts while I don't have to but AS for the complete tank. (which is in my opinion not necessary, since plants are doing in general all right)
greets,
