I'm on day 3 of prazi treatment for my 2 anthias which I saw white stringy poo. They have been in qt for 2 weeks .Now I did a 50% water change before starting prazi and today on the seachem badge I see it change color to .05 so I dosed prime and I might have added a little more a tiny bit more than the recommended. With prazi is this going to cause an issue? I read here that the two together have been known to have caused fish deaths? Is this true?
