Recurrence Of Fin Rot

[Discovery86]

My Betta had fin rot a month or two ago, and I thought he'd gotten over it. Last week I noticed the fin rot is back. I'm currently treating with maracyn. Should I try something stronger if the maracyn doesn't work?

If it worked the 1st time - it should do the trick. . . .

Good luck!!
