Hello everyone. I added a Regal Tang to My DT on 12/9. I purchased from an LFS and I was told they ran a copper treatment. This is the little gal.
I did a 45 gallon water change on 12/12 which is more then I normally do. I usually do a 25 gallon. It seemed to stress her out a bit. I found one white spot on her top fin depicted in picture above. He had two more on the right. I did water test on 12/13
I had some issues with my flow meters which turned off my UV over night. So while troubleshooting I cleaning both CORS and 4 WAV pumps. Which to my dismay temp dropped to 73 degrees. So next one I need clean one pump at a time. Either way it ended up being EMI that through the sensors out of wack but ended in clean pumps. On 12/14 spots were gone. I went out of town On 12/17 returned on the 12/21. Woke up the next morning and 12/22 more spots. Yesterday and today it looks like so tissue damage next the left eye and around the lip. I removed ROX carbon. I performed more water test 12/21 and 12/22. See below.
