HYDROS Set-Up Instructions - How to Add and Configure a Skimmer Water Level Sensor 

Can this be used in on an opaque waste container? I would like to add a sensor to the masteronic waste water container but don't want the cable and main sensor to sit chemical slurry from the masteronic, this would be a great potential option if it works through an opaque container (it is a light blue container, water line easily seen from outside container with minimal light).
