So it’s nothing that’s wrong with my tank, and really something that doesn’t matter at all. It’s just a weirdly random thing that has been that way from when I started this new tank a couple years ago. Coralline grows everywhere, EXCEPT on the overflow box. I’ve always wondered why exactly. I’m sure someone out there, much smarter than I, knows why that is. The tank is a RedSea Reefer 750xxl. The back glass is covered completely in coralline. The center overflow box, which is all glass as well, has never once had any on it at all. The plastic weirs on the overflow are completely covered as well. Just not the overflow. Anyway, that’s my random question of the day that has no bearing on anything. It’s just weird to see this spotless black rectangle in the middle of the tank.
