![]() The Neptune Systems Trident Marine Aquarium Water Analyzer 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. ![]() Requires Neptune Apex or ApexEL with an open 1Link OR a 24V Power and Aquabus cable
