I noticed over the past two weeks or so, there is more green and the start of red hair algae starting to form on the walls of my 8 gal HOB fuge on my 55 gal. I did have the green algae bloom in the main tank, but after running my fuge it has all but disapeared. Should I replace my T8 light bulb (over refugium), or get some snails for the fuge to get rid of some of the algae? I don't want it to get out of control, or is this mornal?
Thanks
