I agree with all of your comments - thanks for clarifying. I think people do go down the rabbit hole of chemical solutions.Sorry I was referring to chemicals like vibrant, Flux, chemiclean and things like that. I think when people use them to treat the ugly phase (if you get one) of a newer tank it upsets the natural progression of things and causes more problems than they cure. These are just my opponons based on my experiences, no science or facts to back them up. I'm not much of a science guy but have great respect for those of you that are. I'm always learning.
