Review on KIB M21VW Micro Monitor System by Tim Wadman

I connected the cables to the tank exactly as directed and connected the cables to the main unit exactly as directed. I only have gray and black tanks so no water pump/fresh water is used. After everything was set, all the lights came on when the tanks are empty, indicating the tanks are full. Unfortunately I did not check the connections before installing the tanks and it will be very difficult to try to solve this problem. There's a small chance I connected it wrong, but I checked and rechecked to make sure everything was plugged in and connected as instructed. You get what you pay for.
