what would happen if i left the algae growing in my tank, will it make problems with the water quality

Well the normal algae won't cause you any problems. Algae is there because its taking nitrates from the water. Unless they all die suddenly nothing bad is going to happen - provided that your plants can still get light.

Otherwise fish and snails will snack on them, so its a pretty good deal.

it really depends what kind of algae you're talking about. diatom algae isn't a problem at all (brown spot), it's extremely common in new aquariums and will go away on its own. other kinds of algae can take over your tank

Some brown and green algae in your tank is cool... like on ornaments and or fake plants. I wouldn't be happy with green water though. That's where you'd have to draw the line.
