Cyanobacteria?

[Reef_kid]

as a biochem/microbiologist i am all for antibiotics, cyano bacteria is inhibited by
Amoxicillin acts by inhibiting the synthesis of bacterial cell wall,
and binds to the ribosomes of the bacteria. inhibiting transcription

erythromycine binding to the 50s subunit of the bacterial 70s rRNA complex

i turn of my protein skimmer and take out all chemical filters.

and treat the tank after sucking all the cyano out of the tank.

I get them by asking the pharmacy (wallmart)
or my family doctor ... say you need erythromycin for acne!

i use about 1000mg per day on my 90 gallon for 2-3 days.

i keep sps/lps/softy.. for 10+ years and i treat cyano 2 times a year...
normally due to temperature raises to induce spawning in bangaii cardnals.
