Hello everyone, so to begin with this question, I have been dealing with some kind of algae for a couple of weeks, I think it's diatoms because it's brown and dusty (the pics looks green but Its definitely brown when I'm up close), but my LFS says it may be a film algae of some sorts that shouldn't harm the fish. So they recommended a UV Sterilizer that can help bring down the bloom I have. I have done some research on them and kind of understand how they work. So my question is, what would y'all recommend for UV Sterilizers to put in my first tank? I have a 45G tank thats turning 4 months old later this month. Any tips and advice is much appreciated! ![Beaming Face With Smiling Eyes :beaming-face-with-smiling-eyes: :beaming-face-with-smiling-eyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Also here are some pics for what I'm dealing with.
