I don't think the chip I have in my tank is that terrible, but I want to get a few other opinions. It's only a 25 gallon. Would you still use this tank?
I’ve got one about 5x bigger than that in my 50 gal in the middle of the top rim of my rimless cube. Mine doesn’t seem to be a problem so I think you’ll be ok. To be safe, maybe do a long leak check (7-14 days) and see what happens. If it leaks or cracks, you have your answer.
