8 days is too long to wait I think. Rally Pro has acriflavine in it that can help with bacteria.Hi Jay, do you think Rally Pro will be a good alternative to try first in the display tank? I read it can cure also fin damage.
Virtually 100% of the external bacteria that infect fish are normally found in aquariums. They just become disease causing if the fish is injured or really stressed, so no need to try and eradicate them.
