In case anyone was curious, this is what an overflow box looks like after almost 5 years of neglect.
And this is what it looks like after 4" of feather dusters, 3 inches of detritus and about 5 hours of my life that I will never get back..
I kicked up a poop storm (literally), so decided to do a 50% water change. Snapped some coral out of water shots.
That is all. Good night.
