Fin Rot Question

I purchased some guppies from the LFS. When I bought them, none had any visible symptoms of fin rot. I guess the stress of the move was enough to aggravate the disease (even after a long drip acclimation into a well-established aquarium!). One fish died overnight the first night. I immediately began a treatment regimen with Pimafix and conditioning salt. The two remaining fish began to show visible symptoms of fin rot a few days ago. One is missing a chunk of her tail and the other is missing most of her dorsal fin and has the white edges left on her dorsal area and a small white patch on her tail. However, both fish are swimming actively and generally don't seem stressed by the illness.

So, my question is... Pimafix tells me I need to medicate for seven days straight (which I have been), but how soon can I expect the visible symptoms to go away?

The fish that didn't make it was gladly replaced by the LFS. The replacement is in his own quarantine tank and seems to be free of fin rot. water parameters are pH 7.2, ammonia 0 nitrites 0 nitrates ~15 ppm.

Pimafix may not cure fin rot. In which case I would try Binox. I am not a great promoter of heavy meds, but sometimes you must do what you must do.

Are you sure the fish are suffering from fin rot? Link here and make sure.

I'm 99.9% sure it's bacterial fin rot.

I also read that Pimafix works great for fin rot when used in conjunction with Melafix, so I whipped up a batch of home-brew Melafix and have begun dosing that. The fish are looking a little better today and are still behaving normally. I'll start a new thread about my homemade Melafix, as it may interest other members.

I have another question. I've been treating my fish with Pimafix and homemade Melafix. The Pimafix regimen started last Thursday, so according to the instructions, this is the last day of treatment. I've been using Melafix since Sunday. The fish are definitely looking a lot better and they're behaving normally again. However, they don't look fully healed.

One fish is still missing a small portion of her tail, and the other still has small whitish areas at the base of her dorsal and tail fins. Her fins have completely grown back, though.

The question is, should I continue medicating until the fish are fully healed and there are no more white areas? Are these white areas just destroyed tissue, or are they a sign that the infection is still active? I just want to know when I can stop medicating and when it's safe to move the healthy male back into the tank.
