Okay so i have a tank that has been running for about a month.(first saltwater tank) I have done only 1 water change and my levels look great. My water is super cloudy and i have a lot of diatoms. I really want to have a crystal clear tank and don’t know what to do. I also have what looks like a million of copepods on my glass. Now to the real problem that’s concerning me. I have a pair of clownfish and it looks like one of the clowns tail stripe is turning grey. Also another one of the clowns has a white pimple looking thing right below his mouth. (pic attached). How can i make this water not look horrible? Also how can i get rid of this white looking pimple on my clownfish.
