Is it possible to extend the probe cable of the Bulk Reef Supply Aquarium Heater Controller? Based on my setup, I need an extra ~2ft. to be able to keep my electronics away from possible contact with water. It appears that a 3.5mm audio cable will work, but I don't want to extend it if doing so will affect its performance. For what it's worth, I have not had any issues with its performance in the last few months that it's been installed.
