Antibiotic Flakes

[Calico3]

Hello All :  Okay I am in the process of taking stock of my limited  supply of " health "  products.  I have some some Antibiotic Red Flake purchased a couple of years back. ( Before Health Canada took all products off the market without Vet approval )  I believe that it is used to treat gram-negative bacteria.

Okay I do know that gram negative infections are the most difficult to treat and I wish  at the time I had also purchased the gram positive flakes. My question is what type of conditions can I possibly use these for with my Aquarium fish. I am presuming that most of the supply should be kept in the freezer. 

Thanks
