If this is being dosed into the water column, the larger the volume of water in the tank, the higher the dosage required to achieve a sufficient effective concentration.. Who knows what that effective concentration would be.. Also, I can see this compound degrading very quickly (or being skimmed out quickly, it is a protein after all).. My assumption is the required dosages would be high given average volumes and what the effective dosage would be if dosed into the water column directly.. It would also be a very wasteful way to administer such an expensive drug.
I've gotten an Rx for Chloramphenicol from the vet to treat RTN, he did require, however, a copy of the protocol I was going to use to treat it to keep on file.
