I have a used Seney aquarium monitor that I would like to sell. I have it all, the Reef Sensor, web server (hard wired CAT5 version without WiFi), water leak sensor and magnetic mount for the sensor. New all of this is costs well over $500. Asking $200 shipped within the USA. All equipment has woked without issue for me but it is being sold as is. No slides are included with are about $10 a month and required for the Seneye to work. If you have any questions please let me know.
