New to saltwater. Have a 55gal tank that is been set up for about 4 months now. Fish in it for about 2 1/2 months.
A couple of weeks ago we got a new Coral Rated LED
light as I read I needed one for the anemones I added. Noticed white fuzzy stuff about 1/8" in length. Not sure if it was there before and just didn't show up with the old lighting, or if it is rapidly spreading.
Does anyone know what this is and if I need to do anything about it or if it is healthy for my tank?
