So I’ve noticed heads in some of my hammers starting to recede and die. What happens is the heads slowly die back over a few weeks. I know it’s probably a bacterial infection but does simply dipping them all take care of the problem? Is the bacteria in the tank floating in the water column? My parameters are good and stable. I change water every two weeks so not sure what caused the issue. Is dipping the only course of action? Thank you for any advice.
