Thank you for the suggestions! I am doing them weekly. Finally got a vacuum for cleaning the gravel and did about 35% water change today.Hey there! That is strange that Kanaplex didn't help. I would urge you to try EM Erythromycin and if that doesn't work you may need to try a dip in something such as methylene blue or potassium permanganate. How often are you doing water changes?
I don’t have Furan-2 on hand but I can get it. Luckily there’s a Petsmart 5 minutes from me.TBH, it looked like a bacterial infection and I'm surprised that the Kanaplex didn't work.
Did you say you had Furan-2. It targets a some different gram negative and gram positive that the Kanaplex does not.
