Hey all, I just got back from a week vacation to walk in the door and see my tank with no lights on and blowing air from the return pump. When i looked at my apex I started pressing buttons to see what was wrong and noticed that the display was frozen. I also tried using the app but nothing was happening. I unplugged the system from the wall and plugged it back in and the screen turned off and is not coming back on. I also noticed that the energy bars have a blinking yellow light. I'm not sure when this happened as i have not been able to contact the person who was taking care of my tank yet. Please help me trouble shoot my apex!
