Brown algae on glass ??

[Animal-Chin]

Ya that glass algae is totally normal, just get a magnet cleaner and rub it off daily. I clean my glass every day after I feed. The only time I've never had some on my glass was when my tank went fallow for 2 months and I has no fish. My nitrates were at 0 and I didn't have a speck of algae, add a fish or two and back it comes.

2 days from changing the water and cleaning the glass this brown color shows up in glass! I have a 24" t5 Ho 4 bulbs (2 blue plus and 2 coral plus)
