I've had good luck with API triple sulfa for fin rot. Havent tried it on cottonmouth, tho the package indicates it can be used for that, too. No luck with Maracyn-2 for fin rot.

I can support the fact that Furanase is effective for fin rot (bad cases).
Columnaris is hard to treat (based on my experience) and some Kanamycin might be useful.
I am really surprised that Furanase didn't wiped out your biofilter after the first dose. It did on mine but I was using a small qt tank. Check parameters daily, please.

Me too! I have been checking the params daily on the big treatment tank as well as the 10g with the betta being treated, and both bio-filters are 100% working.

When you used Furanase, how long did you use it for and about how many days did it take for fish to look completely cured?

Yesterday I woke up to a dead guppy in there, and it wasn't even one that had any "rot" of any kind. So it was either too much salt to handle or too much medication. I did about 45% PWC, adding new water back slowly over the evening, without any salt or meds added last night. I haven't replaced carbon yet because I plan to continue treatment. There is still medication in the water because it's still tinted brown. Whether or not it's "active" after the first day, I don't know. I assume it does accumulate over the course of treatment and reaches it's highest concentration on the last day of treatment.

When I saw the dead guppy, first thing I thought was "ammonia spike," but the ammonia/nitrite is 0. The test is working accurately, confirmed by testing the 30g which is fishless cycling.

What about temperature? I have read article after article on these types of infections. Some say increase temp, some say to decrease it. Some say columnaris is gram-positive while others say it's gram-negative. If they can't agree on these details, how do I even know if the treatment info I'm reading is accurate? :( So, I brought the temp back down to their normal, which is 78-79F.

Sometimes columnaris can be stubborn and require more than the label dosage level. I have always used EM for columnaris and occasionally had to use a double dose level to knock it out.
