Saw this at MACNA 2017 and received email today that the Reefbot is available for early adapters. Anyone using, or going to purchase this (#tiredofwaitingfortrident).
"ReefBot uses traditional reagent based method to autonomously measure the levels of the most common parameters in your tank. It currently measures Alkalinity (Alk), Calcium (Ca), Magnesium (Mg), Nitrate (NO3), Phosphate (PO4) with more parameters added regularly."
