I just recently was given a 75 Gallon Salt water tank it has been set up for over a year and just noticed the other day that there was these white bubble looking things on the rock growing there is 2 now and they are new.I thought maybe it was bubble algea but they are white in color and not green. I have circled them in red can anyone tell me what they might be and if they are harmful...
