Chip in sump

[Huff747]

Seeking opinions on this shard of glass that came off my Red Sea Reefer sump. Not sure when it happened. Had to take the tank down for new floors and it was when we went to move it back we found the shard laying right next to where it came from.

It really doesn't take very much applied pressure to chip tank edges/corners. As this is a sump I think you'll be fine. You may want to apply a gob of silicone off it just for peace of mind.
