Then why did you post? If you'd like to split your responses for a discussion of why antibiotics should not be used in the aquarium, I am interested in hearing that.

Many bacteria are naturally resistant to specific drugs, so using the proper type of antibiotic is of the utmost importance. For example, gram-positive bacteria are often unaffected by tetracycline and streptomycin, while gram-negative bacteria may be unaffected by ampicillin, penicillin, erythromycin and sulfa drugs.
Some bacteria may also be unaffected by the usual dose, but are susceptible to a higher dose.
Here is another good example. Mardel Laboratories makes Mayacin and Mayacin 2. Mayacin is erythromycin based and is a gram-positive bacteria treatment. Mayacin 2 is mincycline hydrochlor based and is a gram-negative bacteria treatment, as well as sufficiently absorbed through the skin to treat internal infections. Since most bacteria that cause disease in marine fish are gram-negative, and can quickly become systemic, Mayacin 2 would be the most effective choice.
You have to take into consideration that you will not be able to determine the exact type of bacteria you are dealing with, mutated strains can be produced, and both bacteria might be present. Broad spectrum antibiotics, ones that kill both gram-negative and positive bacteria, such as neomycin, chloramphenicol, nitrofurazone based products, skin absorbed kanamycin sulfate based antibiotics such as Kanacyn/K-Mycin, and secondly tetracycline, are usually effective treatments. Aquatronics makes an ultra-wide spectrum antibiotic blend of nitrofurazone and kanamycin called Spectrogram that may suit your needs. If after a few days of using a particular antibiotic there appears to be no or little improvement in the health of the fish, try another one. These are just a few of the many available products on the market, so do your research to insure that the medications you choose are safe to use in conjunction with each other, if you decide to mix them.
The over use of antibiotics for treating fish is the same as with people. The repeated or continued use of antibiotics creates selection pressure favoring the growth of antibiotic-resistant mutants. Our advice is not to use antibiotics as a cure-all treatment whenever you feel the fish "might" need it, but only when it is necessary.

The reason I commented on it was I was asking for a thread split as I felt my question had been "hijacked". As I stated, I would be interested in a discussion on the ethical use of antibiotics in the aquarium as a learning exercise for myself, however not in this thread.
Perhaps it is a cultural or language confusion, but I found the tone of both Philippe Burnel and Bas Pels to be quite condescending. Implying that I wouldn't agree that people are more important than fish because I do not have any qualms with responsible use of antibiotics in the ornamental fish hobby.

Yes, there is. I recently had a run in with some nasty blue-green algae in a planted tank and treated it with erythromyacin (spelling?). I was considering using to to get rid of the cyanobacteria in my Cichlid tanks and was concerned about "crashing the filter"...
Oh...and I also help out on another Cichlid forum in the "Health" section, so I try to learn as much about these subjects as I can...

Then you would have to dose with your antibiotic again. I see that as a rather extreme course of action. As far as I am aware there are no antibiotics available which are specifically active against cyanobacteria only.
I think I would decrease the light for a while. Lower the agitation from the filter - switch to a sponge filter if you have to (temporarily), this should increase the amount of CO2 in the water which is something I believe cyano doesn't like. I would increase the water changes too.
