Algae problem

Hi everybody.

I've observed that some kind of algae have started to grow on the glass of
my tank. It's still impossible to say which is algae color but it seems hair
shaped.
How can I prevent that this algae fullfill tank?
I've reduced the daily food amount and light. It's enough or I will need to
introduce some chemical to stop them (last chance)?
Thanks and best regards....

One other suggestion I would have is to introduce some rosie-barbs into the
tank if they are compatible with the existing species. They are the only
fish I've had that have a great appetite for string/hair algae.
