Green and brown spot algae

[Magnum-]

Hi guys,

I'm currently keeping a big tank with plenty of java ferns, anubias nanas and they all seem to have algae grown on them. They are dark green turning dark brown but is quite easy to scrape them off the plants. Anyone can give me any tips on what kind of algae this is and what anti algae measures i can take to get rid of it?

What fishes or shrimps help? Is there any anti algae medcine?

Many thanks.

Regards,

Magnum

You need to put in more info about your tank spec and etc. No fishes or shrimps can solve algae problem. Medicine, yes. But the point here is growing plants.

What I experience is I had high light which caused such problems, because the other nana I have lower and covered do not have such problems
