So I've had this roughly 50 gallon tank for just over a month now. I've done 1 water change of about 50% about 2 weeks ago. And I'm now noticing this brown stuff on the front glass, there's some on the back glass too. I'm just wanna make sure it just algae, or is it something I should be worried about? Because I always thought algae was just green, but this is brown. And there's a few black spots on a fake plant I have. I haven't seen them anywhere else excepts the 1 plant, are they also normal?
The fish I have if necessary:
6 black skirt tetras
6 Emperor tetras
5 neon tetras (1 died for unknown reasons, a while ago, I gonna get a few more neon soon.)
I've got a good Ciano filter that has a Water Clear and protect cartridge, and a Bio-Bact cartridge.
I have also cleaned the filter sponge recently aswell.
