You know how when you first set up a new tank the tank walls and everything is covered with small bubbles. Well all of the bubbles the was on the tank walls are gone but for some reason there are tons of bubbles covering my heater and I wiped them off with an algae sponge and within an hour it came back then I did it again but it came back. So will it go away on its own or what can I do to get rid of it because it looks stupid and I want it gone. Advice welcome.
