The Apex line includes the base controller, Trident (automated alkalinity/calcium/magnesium tester), DOS (peristaltic dosing pump), ATK (auto top-off kit), Cor (DC return pump), and a wide range of expansion modules.
Apex Classic, Apex EL (entry-level), and Apex Jr. The full-fat Apex supports 24+ outlets, dozens of probes, and infinitely programmable rules via APEX programming language.
Pulls a sump sample every 24-72 hours and runs alk/cal/mg titration. Logs to Apex Fusion cloud. Eliminates manual testing for the parameters that matter most.
Two-channel peristaltic dosing pump. Pairs with Trident to auto-correct alk/cal/mg out of range. The standard for hands-off reef chemistry management.
