Hello, this tank seems to have a small millimeter or two crack in the glass/ poxy for the front panel (in the front right corner about inches up). I hear a creaking noise 3x a day and do not know what to do.
This is a fluval 32.5g. It's been up for 7 months. The stand is for a 40-50G tank and realized the front right part is uneven on support by 2-3 millimeters.
