The dosage and what to use was told to me by the rodent breeder I sell most of my extras to. I did just take him at his word at that point, and he said a small pinch, but I have done some research since I have a print out at home for dosing rats on the same antibiotic under a different name, I think it's teramycin. But would have to check at home to be sure

I have read that if you black out the bottle it can last three days but I don't have experience with it in gallons.

I use 8 oz. water bottles for medication and the biggest I would go is 32 oz. and I don't have a watering system in my quarantine area

My experience with it has been the sneezing and wheezing stops around day three or four.

Has anyone tried the F10 via nebulizer just to wonder, I have read this being used for rabbits
