Hello, I am new to the hobby. I started a 55 gal tank about 3 months ago. I have a few issues that I could really use some opinons on if anyone has any ideas. First off, I have checked all my water parameters using a nutrafin master test kit which is a 10 parameter test kit and everything is where it should be. I have a refractometer and my salinity is maintained at 1.024- 1.025 That being said, the issues I have is the brown spot on this coral that had formed. It started to get healthy, or so i thought, and then it came back and it seems to be staying the same. Any suggestions? Second issue I have deals with these white things that are forming on my glass and I have no idea what they are? Possibly a parasite? I also have white spots on my blue hippo tang which I can't figure out what that is either. I did a fresh water dip yesterday which reduced the spots by about 70 percent so I plan on doing another dip tomorrow to hopefully take care of the rest. I don't have any pics of the hippo tang but they are white bubbles and black dots all over if anyone has any idea what that could be. Any suggestions or comments are much appreciated!! Thank You!!
