HELP.....fin rot cures?

[tim the toolman]

I currently am having a fin rot issue and was wondering if someone could tell me what the best product to cure this is? I will be quarantining the fish asap.

How old is your tank?
Does it (fin rot) happen on more than one fish?
Do you see any other abnormal signs on the fish, like white dots, red stripes, etc...
Do you observe a fish bullying other fish?
