It's Tetracycline pure and simple

Tired of $75 to ??? (Where is the limit?) doctor's visits to get an antibiotic for an infection? If you are savvy enough to know when you have what you may want to know that the exact same antibiotic is available to dope your fish tank and retard the growth of unhealthy bacteria. And you won't go to the pharmacy and pay $50 to $100 for 30 to 50 caplets. This is a bottle of 100 caplets for less than $28 or at least it was when I reordered from the vet supply house that ships it.

(Where I also found 100 - 500mg caps for the same price.)
