I just moved and when setting up this tank noticed a small chip. Its a 65 gallon and this was previously in the back corner so no saying how long its been there. This used to be a planted freshwater tank, but I was hoping to finally dip my toes into salt water. Im leaning towards it being fine, but what would you do? Is epoxying or siliconing it over it a good idea? Vertical length is smaller than a quarter. Maybe nickle sized.
