I'm currently treating a few fish with what I think is columnaris. Two rams, one guppy, and one rummy-nose seem to have it. I'm on the 4th day of treatment and there is no signs of improvement. Does this take a while or is this being ineffective?
My regimen was this:hurricanejedi said:The directions say to dose for 5 days. If needed it says to dose for another 5 days. I'm not sure if its working so maybe should use Maracyn 2? If I did a second course of this stuff then I would really want to change the water. Is this stuff only active for a day, hence you dose daily, or does it build? Therefore not wanting to do water changes?
