I was wondering if there was anything I could do about the algae against the glass on the sand bed? I see it in a lot of the pictures of other members tanks and I think it's pretty unsightly. I don't have any other algae on the rest of my tank. Can I stir is up with my forceps or will that release toxins? I don't have a phosphate meter but my nitrates are undetectable and I am running GFO through a HOB filter. I use RO/DI water only and do 15% water change weekly. Thanks.
