Chipped bottom corner

[akinaz]

I got this 60 gallon rimless for super cheap and when I got home I realized there is this chip on the overflow bottom corner . Is this done for? I planned on re sealing the tank anyway bc the silicone is in bad shape. Should I look into getting a new glass pane or would it be ok?
