Have a Tunze 5017 ato that I no longer need. This is the one with optical eye and float switch for high level. Only issue I have had with it is the power cord is very touchy and will possibly turn off power if moved. Best would be mount where it wont accidentally be bumped or use a bracket instead of the velcro. They sell 3D printed brackets for cheap on ebay. Will also include a backup controller ( the one in plastic bag) that I think was replaced because the eye wasnt reliable. They need to be cleaned regularly or will fail. Tunze are reliable if you maintain it but I wanted something different. Have directions but not box. Asking $75 shipped lower 48
