The Neptune Systems Apex TRIDENT is an advanced automated monitoring device designed specifically for saltwater reef aquariums to continuously track the three critical parameters essential for coral skeleton growth: alkalinity, calcium, and magnesium. By utilizing a proven titration method with micro-drops delivered via a stepper-motor driven peristaltic pump, this system removes the human error associated with manual testing and provides consistent, reliable data directly through your aquarium controller connection.

This device connects seamlessly to Apex controllers via a 1LINK port or AquaBus with an external power supply, featuring dedicated tubing for drawing tank samples and expelling waste. The internal design excludes pH probes to minimize calibration needs, focusing instead on high-precision measurements with alkalinity accuracy of +/- 0.05 dKH and both calcium and magnesium accuracy of +/- 10 ppm. Operating at a default schedule of four alkalinity tests and two each for calcium and magnesium daily, the system offers exceptional value with reagent costs averaging approximately twenty dollars per month.

This monitoring solution is best suited for serious reefkeepers who demand scientific-grade data to maintain stable water chemistry in complex coral systems without the hassle of daily manual testing. Ideal for advanced hobbyists managing Large Polyp Stony (LPS) or Small Polyp Stony (SPS) dominated tanks, it empowers users to make precise dosing decisions based on real-time trends rather than sporadic snapshots, ensuring optimal growth conditions and long-term stability for sensitive marine invertebrates.
