isn't ultraviolet sterilizer quite expensive? the antibiotics is about
$4-$5/pack for the full treatment regimen.. I would think UV sterilizers are
much more expensive...?

I suppose I can do 30% water change every other day for a while to see if
that will reduce any pathogens.. (seems like water change may be in order
anyway to fix the GH creep, whatever the cause was)

I guess I better hold off on adding the CO2 injector (nutrafin) that I
bought few weeks ago, in the expectation that I will finish using the
flourish excel... CO2 injection will probably mess up the pH even more from
the sounds of it..?

Hi all,

I've been trying to figure out what may be stressing my fish... before I
start adding wide-spectrum antibiotics or anti-parasitics, I wanted to
rule
out stuff that is more prosaic than some insidious infection...

Have you considered an ultraviolet unit before spending the bucks to
dose you tank with antibiotics? That would be my next step, other
than the moving GH figure that is being discussed in the thread. The
moving PH I would attribute to the natural CO2 cycle of your tank.
