patch

Frogspawn coral looks happy enough but I noticed this strange pinkish with white outer mark on the stalk this morning. Just wondering if it’s anything anyone had ever seen before and if it is something I should be concerned about?

I got a really good deal on a deep blue 57g reef ready rimless tank, but the center overflow takes up way too much space in the display. I'd like to remove the overflow, patch the holes in the bottom, and drill new holes in the back to plumb a low profile overflow and return. Has anyone done...
