The Neptune Systems Trident ACM is an automated testing device designed to continuously monitor alkalinity calcium and magnesium levels in saltwater reef aquariums. By eliminating the need for manual test kits this unit delivers consistent high frequency data that helps reef keepers understand consumption trends and detect issues early to maintain long term stability. It integrates directly with compatible Neptune Systems Apex controllers to log every test result into Apex Fusion for detailed tracking over time.

This system utilizes automated titration combined with an internal colorimeter to replicate standard chemical tests with precision and repeatability. Users can test their aquarium water up to 24 times per day while receiving seamless integration support for Apex Fusion graphing alerts and automation actions. When paired with a Neptune Systems DOS or DOS QuietDrive dosing pump the Trident becomes the foundation of a closed loop testing and dosing system that automatically adjusts additive delivery to maintain target parameters.

This advanced monitoring solution is best for serious reef hobbyists seeking maximum stability in their coral tanks who want to remove human error from parameter management. It provides peace of mind by ensuring critical water chemistry remains within safe ranges around the clock without constant manual intervention. The included two month reagent kit allows users to begin automated testing immediately upon installation while planning for future maintenance needs.
