Hello - another newbie question -- I have a "see through" tank built into a wall. The aquarium is viewable from "front" and "back" but the two "sides" of the tank are not accessible/viewable. I have been cleaning the front/back glass of the aquarium but letting the sides grow algae. I like what it looks like but wanted to ask if letting the algae continue to grow on the glass will cause any problems later on. thank you
