Drilled tank crack

[hottrash]

Was drilling the top of my tank and theres a very small crack on the top of the hole that's about 3/4 of an inch inside the glass. It's a 90 gallon I was gonna to use as a refugium and I'm wondering if it's going to be fine. I'm hoping it would be if the crack is above the water level and if it does web out it's going towards top of tank.

You can always get another piece of glass and silicone it on the inside and even predrill it if you’re concerned about it.
