I’m sick in bed and have been for a few days. My husband is doing the best he can trying to take care of the tank maybe a week ago after a 12 to 15 gallon water change in my 120 gallon tank, I had a huge bloom. I ended up researching here and turning off my lights for three days. This made my Rose Tip mad and she moved from the spot she had been in for two months. Since she has been tiny…. But today my husband told me something was going wrong and showed me these pictures. This is my first name so I don’t have a clue. What are these brown clumps? I’m stressing because my husband left the state and won’t be back till the end of the week. Water have always been “ normal ranges” but I have not tested today and need to save up some energy…. I’ll get to that part though but if we can start with the blobs? Tank mates include tiger CONCH, tiger cowrie, Cleaner shrimp, watchman, and pistol, color, bicolor angel, fire, Fish, powder, blue tang, and hippo, tang, clowns, and a bangaii cardinal. Ty!
