For a guy on another site to see there is no algae. None. And I don't mind some algae in the display. This tank is in the garage. Temporary tank til I figure a wall for another tank sitting in the garage. This tank I've had since January. No water changes. I brought it home and went straight to scrubber. There are fish but they're camera shy. Not too many corals because it's a temp. set up. Bought it for the rock and fish for a very good price. If you go through my album. You'll see my ATS is a little big and I haven't screwed with it since It's not permanent. Built it before I read new size guidelines. I'm dragging my feet at the new set up.
