I’m talking аbουt actual Tet-HCl concentrations rаthеr thаn thе weight οf lіttlе tablets уου bυу frοm thе pet store! Anyone gοt аnу іdеаѕ?
500mg/20 gallons is exactly what you want to be dosing. However, there are far better choices for fin rot (minocycline, nitrofurazone, kanamycin, sulfonamides, etc.). If you do use tetracycline, be sure to keep the tank dark, as tetracycline degrades with exposure to light, making it more toxic. Regardless of your choice of medication, remove any activated carbon from the filter, as it will remove any organic compounds (like drugs).
