This pairing combines a Neptune Systems Apex controller with the Trident ACM automated water analyzer, which continuously tests alkalinity, calcium, and magnesium in saltwater reef aquariums. Using automated titration and colorimetry, the Trident can run up to 24 tests per day and logs every result to Apex Fusion for graphing, alerts, and automated dosing when paired with a DOS pump. It requires a compatible Neptune Apex controller (A3 or A2 models) to operate.
