Because of the new plants present, I would not
recommend a blackout.  I have successfully used
erythromycin to wipe out cyanobacteria (BGA).  First I
fixed the nutrient deficiency, then treated with EM. 
If you don't fix the imbalance in your tank it will
come right back.  The EM will not wreck your
biological filtration.
"Someone recommended Erythromycin.  Can someone tell
me what the dosage would
be for a 135gal?"

Dose at 1/2 the recommended dosage as stated by the
"Someone else recommended Maracyn (sp?).  That is
pretty expensive around here."

You can use Mardel labs - Maracyn or Aquarium
Pharmaceuticals - EM tablets.
"Do antibiotics hurt snails or shrimp?  And do I
remove the carbon from my filter?"

My snails were unaffected and there is no reason to
believe it will harm shrimp.  You must remove the
carbon from your tank.  As a side note, your plant
tank does not need carbon as it will only sequester
nutrients needed by your plants.

Good luck,
