Με την erythromycine δεν θα έχουνε πρόβλημα τα φυτά σου σε αντίθεση με την συσκότιση.

Εγώ είχα εφαρμόσει την μέθοδο από το The Krib :



Day 1.
Add 2.5 mg/L erythromycin. If you have a protein
skimmer, turn it off. I believe it will inactive a lot of the
antibiotic through coprecipitation with protein. It will,
however, be very usefull later.

Day 2.
Add 2.5 mg/L erythromycin.

Day 3.
Now you should see a lot of dead blue-green bacteria
floating around in the tank. Increase filtration (a second
mechanical filter if possible) to get rid of it. If you have a
protein skimmer, turn it on. The critical thing now is to get
rid of as much protein (dead bacteria) as possible to avoid a
peak of ammonia.

Day 4.
Most blue-green bacteria should be dead by now. Try to
clean out as much as possible of the dead stuff. I use a jet
stream of water from the outlet of a canister filter to remove
it from plants and decorations. Combined with the second
mechanical filter, this works fine for me. Let the filter work
for a couple of hours then make a 50% water change. Add 2.5
mg/L erythromycin.

Day 5-7.
Wash the mechanical filter at least once a day. Keep
check on ammonia and nitrite but do not change any water
unless absolutely necessary. The extra filter can be removed
as soon as the water clears up.

Day 8.
Make a 30% water change. Add 1 mg/L erythromycin.

From now on, resume your normal maintenance.

The concentration I use is in theory a bit high and
getting up where it should starts having an effect also on G(-
) bacteria. When I started using erythromycin I had problems
using lower concentrations in the tank. It was not very
effective. It might be time to check it again.

One word of caution. Only use erythromycin when you
really need it or you might end up with blue-green bacteria
resistent to the antibiotic.
