How big is the tankI have worse chips then that on the corner of one tank and it hasn’t been an issue. I think you’re fine.
So I should be good thenI thought that might have been it but I also thought I might have been not seeing this huge chip you could have been talking about.
In one of my tanks, I think it's my 20 gallon, I have a nice size chunk knocked out of the edge. Think the size of your pinkie nail with abut 1/4 of the size taken out. Been up and running for several years and I have not encountered any leaks.
