I am bringing a tank back to life that I did not care for about 2 years. During those two years, there were still fish and crabs, etc. It is 135 Marine FOWL tank. As I update the filtration, lighting, etc, there are some nodules growing. They are soft to the touch, clearish-whiteish. I have no idea what they are and if they beneficial or harmful to the tank.
What is it?
