So I had some brownish-red algae in my tank that started about 4-5 weeks ago. I continued weekly water changes and cleaned the inside walls of the tank to get rid of any algae on there and didnt use any kind of "algae-fix". After a couple of weeks i noticed it was getting less and less. It was looking pretty good last week, but now i got a whole bunch of green algae as soon as that brownish-red algae had disappeared. Anyone know anything about this and how to get rid of it?
