Glass chip

[rastaangel]

I would just go to glass shop and get a peice of SALVAGE 10-12mm and replace the panel. Its a easy fix IF you know how to properly rebuild a tank, other wise it will just cause more issues with leaks and other stuff
OR
If that panel is against the wall and not seen you could double glaze it with another peice of glass if your afraid of rebuilding the tank. I have done that a few times on larger tanks, infact I did it on my uncles 260g turtle tank
But I would replace the side.... Just cuz I know what it feels like to come home and find a tank flooding your place
