hello,
Thanks for the tips.
Unfortunately I only speak very bad English and therefore use a translation program. Could therefore arrive a little bumpy.
@ Patrick
In my aquariums are Najas guadalupensis and Ceratopteris.
Since there are no plants that have rooted, I think I would have to make do with a thin layer of gravel or black sand.
I put the aquarium in order gradually and tell then how it has developed.
greeting
Matthias
