Likewise. I clean the front glass with every water change, whether it may seem to need it or not; green dot algae is invisible at first, and doing a weekly clean with one of those aquarium sponge scrapers keeps it from getting started. I do the other walls if I see algae forming. Keeping it off the plants is essential or it will suffocate the leaves. But live plants do help to keep algae minimal; ensuring the light intensity and duration is not greater than what the plants can use, which means in balance with the nutrients, will keep algae at a disadvantage.
Algae is natural, it is a part of every aquatic ecosystem, so expecting an aquarium to be free of algae is unrealistic. But keeping it within bounds, under control, is the goal, and live plants plus light that is not beyond the plant's requirements will do this.
