First time ordering from jehmco, i called them up and they need me to email out a form and ship out tomorow. I am going to order the nitrofurazone 100 mg, to be safe im going to go find the API furan tomorow if i dont see improvements tomorow when i do a water change tomorow morning. currently from the box Last packet of API fungus cure (can only treat 100 gallons), my water is green from the medication. I am going to do a 20$ water change and add more pimafix and melafix.
does this look like a fungus or bacterial infection? Im scared that it may be columnaris, as then i have to nuke the entire tank with the nitrofurazone for a while.
