The Neptune Systems Trident ACM is an advanced automated testing device specifically designed for continuous monitoring of alkalinity, calcium, and magnesium levels in saltwater reef aquariums. By eliminating the need for tedious manual test kits, the Trident provides consistent, high-frequency data that empowers reef keepers to better understand consumption trends, detect potential issues early, and maintain critical long-term stability within their aquatic environments. This innovative system seamlessly integrates with compatible Neptune Systems Apex controllers, logging every test result directly into Apex Fusion for detailed graphing over time and the configuration of custom alerts or automated actions. It includes a comprehensive 6-month reagent kit, enabling precision testing up to 24 times per day, ensuring repeatable results. When paired with a Neptune Systems DŌS dosing pump, the Trident forms the core of a closed-loop system, automatically adjusting additive delivery to precisely maintain target parameters using automated titration and an internal colorimeter for accurate chemical analysis. The Trident ACM is an invaluable tool for dedicated reef aquarists, particularly those utilizing Neptune Systems Apex controllers, who seek unparalleled accuracy and automation in parameter management. It is ideal for maintaining the delicate balance of a thriving reef, providing peace of mind through continuous monitoring and the ability to proactively address parameter swings, ultimately saving time and ensuring optimal conditions for corals and marine life.
