Reef Kinetics Mastertronic Automated Water Tester

Selling my Reef Kinetics Mastertronic. This is the serial number RK-0394 unit. If you're into saltwater tanks you know how much of a pain testing can be, so this thing basically automates the whole process for you. It's been used but it's a solid piece of gear for keeping your parameters in check without having to do the manual chemistry sets every day. Works with the app and everything. Let me know if you have questions.
