Hi, Thanks for your comments !
Some news......
I planted some Eleocharis vivipara (in the corners)
in the set up of this tank. The result was not good for me because the tank became some chaotic (vivipara is a great invasive plant).
I have left to grow all the plants during two weeks
Before...........The Chaos
After......................trimming, water change + BrightyK + Green Bacter
Regards
