Dionigi, are you a microbiologist or expert on this subj? I would like
to know what "happens" to anti-biotics in a closed system like an
aquarium. If, for instance no carbon is in the filter (does carbon
remove it anyway?) and only small water changes are done, does the
anti-biotic remain in the system, and does it remain "active"
What ARE anti-biotics anyway? Are they "active"? Alive? How do they
work? Do they all work in the same way?

In my limited experience, H. polysperma sunset LOVES light. it strives
to get to the surface, and then starts getting bushier and taking on
the red colour. If your tank is very deep, this would explain the
legginess. Have you tried pinching out the growing shoot?
