I have a 55 gal sw tank that has been up and running for about 6 mo or so. I am just getting over a bad case of ich that I treated with a store bought treatment. I do not remember what it was called but Kordon? made it. Now I have alot of stuff growing everywhere. They are white and look like cotton balls except they are hollow and cone shaped. They are growing but most are still pretty small. I have tons of them though and am worried about their affect on my tank. I also have lots and lots of white curly q's all around my tank that have been there for awhile and am wondering what they are. Any ideas??
