Algae cleaning

Looking for some advice on the how often do we need to do the algae cleaning, especially on the non-visible glasses (base and back). My self never clean these 2 glasses sine day one after 3 years. Always have full of brown algae on these 2 sides. Question is if this algae is good for the water condition for long terms, just like in the natural habitat? Or this will create a platform for some unwanted bacterial or parasites that can be harmful for the aro in long run.

is this a crappy topic? no one in the town do not clean the bottom and back glasses at all......................
