It's been 3 months since switching my nano reef into a modest 45 gallons. The golden brown diatoms were really frustrating cause they would show up again about 2 days after a water change. I didn't think there would be any as this was an already established tank.
They weren't harmful to any inhabitants, just looked kinda dirty on the nice white sand bed. But now it's finally starting to look the way it should.
P.S.
My yellow tail damsal count is still at 6 and no scwabbles going on that I can see. Soo..... im one happy reefer.
