Hi, I've had this freshwater tank for at least five years now and I don't remember anything happening like this before (or possibly I never took notice). About a month ago white stringy stuff started growing on the glass of the tank. We didn't do anything at first because we thought it would just go away, but now it is spreading to the fake plants (not the real ones). I am starting to worry because we have some baby fish in the tank as well as our 9 adults, and was wondering if this would be of any harm to them? First of all if anyone could just identify the stuff that would be great. And if anyone knows how to get rid of it that would be even better. Thanks so much!
