The Neptune Systems Apex TRIDENT is an automated testing device designed to continuously monitor alkalinity, calcium, and magnesium levels in saltwater reef aquariums. By removing the need for manual test kits, this unit delivers consistent high-frequency data that helps aquarists better understand consumption trends and maintain long-term stability within their systems.

This device connects directly to a compatible Neptune Systems Apex controller and logs every test result into Apex Fusion where results are graphed over time and can trigger alerts or automated actions. Utilizing automated titration combined with an internal colorimeter, the TRIDENT replicates chemical testing processes used in manual kits but with far greater consistency allowing for tests up to 24 times per day without user intervention.

This monitoring system is best suited for serious reef keepers seeking precision and automation who want to detect issues early through Apex Fusion graphing and alerts. When paired with a Neptune Systems DOS dosing pump, the TRIDENT becomes the foundation of a closed-loop testing and dosing system that can automatically adjust additive delivery to maintain target parameters effectively.
