16 gallon bio cube is having a continuous leak in the front of the tank, at the top , does anyone know how to prevent such high water level in the tank and the first and second compartments are the same heights, the return pump section is normal levels. I’ve had this tank for years set up and it does very well but lately there’s salt water dripping out of the front under the plastic molding , I took off the plastic hood , the LED lighting stopped working
