Jessie Posted December 4, 2021 Share Posted December 4, 2021 I have around 10 fish in my 80 gallon DT. About a week ago I started dosing Alk through my Dos. The plan was to increase it slowly over the course of a week from 6.7 to 9ish. I made sure not to exceed 1dkh per day and everything was going fine until I reached 8.8 range. One of my tangs started developing what appears to be Ich. I shut down the Alk dosing and started doing some water changes to bring the Alk down a little. Right now it’s sitting at 8.15, it’s been a couple days and my tang is about the same. Not really better or worse. He’s eating normal but a little moody and skiddish. I’m assuming this was due to the Alk but I’m not positive because none of the other fish were affected. Did I do something wrong? What should I do at this point? I have a UV set up and running 24/7. I can set up a QT pretty quick. Quote Link to comment Share on other sites More sharing options...
