Just want to see if others are identifying this is as diatoms/brown algae. I converted my tank to planted last month, and even though I cycled with my old tank gravel it could still be considered a new tank. Tank details are in my aquarium link at left, but parameters are all in the normal range. My lights are on 7:30am-11:30am and then again from 5-9pm. The tank is near a window but I keep the blinds drawn. Thoughts?
