Ok, I have atleast 3 tanks that have been exposed to mouth fungus, possibly a 4th...

I put the fish infected into the same tank. Well, they have died. I didn't find out what it was and get the treatment until it was too late...

I did treat all 4 tanks today before the last 2 died. Now there are no visibly infected fish.

The directions on the bottle say to treat the tanks once a day for 7 days.

Now the question: Should I continue treating the tanks for 6 more days? and if so, should I also continue to treat the now empty tank?
 
Columnaris is actually bacterial (despite the name "mouth fungus") so Pimafix is probably not an effective treatment. I've never treated it so I hesitate to give you any further advice. Hopefully someone else with more experience will pop in.
 
I don't know anything about the product you are trying but if you can get hold of 'Interpet' products; their 'Anti fungus and finrot' treatment worked really well for me when one of my fish got a cotton wool growth on its dorsal fin. Cleared up within 24hours. Also works for mouthrot which it sounds like yours had.

Whether the disease is still lurking in the tank I obviously don't know but this stuff seemed to do the trick on getting the fish healthy again and I haven't seen any others showing signs of it.
 
As Jpappy says, this is a bacterial problem so we would normally recommend Melafix rather than Pimafix in this case. However, Pimafix does have some anti-bacterial activity as well as anti-fungal.

If you can afford the Pimafix you could treat the empty tank to help lower bacterial loading in there, although I don't know how much of an effect it would have, as I don't have any info on it being used as a sterilising agent in this way. If not, you could leave the tank empty for a while instead.

For the other tanks, you may as well finish the course of treatment, as Pimafix does not have any adverse side effects like some medications.

Columnaris is considered to be present in most freshwater environments all the time, but an outbreak of illness from it is usually linked to the fish suffering some kind of stress, which has weakened them and made them more susceptible.
