The Trident is an automated testing system that regularly tests alkalinity, calcium, and magnesium in your saltwater aquarium — and then communicates this information to your Apex so you can get alerts, and change your dosing. When combined with the DOS (available separately) it creates a fully automated system for the proper dosing of supplements, maintaining them at consistent levels.

• Automatically performs Calcium, Alkalinity, and Magnesium tests
• Includes 1-month of reagent
• Combine with Neptune DoS for automated dosing
• Programmable alerts for out of range parameters
• Data is graphed for easy to comprehend tank stats
• Can be set-up and integrated with your Apex in less than 15 minutes
• Empties used reagents and sample into an external vessel (not included)
• Up to one month of testing before reagents need changing; based on 4-Alk, 2-Ca, 2-Mg tests per day
