It includes the Apex Pro base unit, Energy Bar 832, lab-grade double-junction pH and ORP probes, temperature probe, optical leak sensor, 15 inch Liquid Level Sensor, Aquabus cable, calibration solutions, and expanded onboard ports. For large reef systems, SPS-dominant aquariums, equipment-heavy installations, controller boards, fish rooms, and mission-critical systems, the A3 Pro is the model that minimizes what needs to be added later.\u003c\/p\u003e\n\u003cp\u003eWhere the standard A3 provides core control and monitoring, the A3 Pro adds ORP monitoring, liquid-level measurement, optical leak detection, more FMM capacity, and 0-10V variable output capability.

ORP monitoring can help identify unusual system changes, the 15 inch Liquid Level Sensor provides depth-based level awareness, and the optical leak sensor improves leak detection capability. The additional FMM port also leaves more room for future sensors compared with the standard A3.\u003c\/p\u003e\n\u003cp\u003eThe display module and salinity probe are not included and are available separately. The A3 Pro has the broader hardware platform for advanced monitoring and control, but final system capability depends on connected accessories, programming, installation, and how each outlet or sensor is configured.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSetup and Installation Directions\u003c\/strong\u003e\u003cbr\u003eInstall the Apex Pro base unit and Energy Bar in a dry, ventilated, accessible location with drip loops on all cables. Mount probes where readings will be stable and representative of the aquarium system, typically in a sump area with steady water movement. Connect the Energy Bar using the included Aquabus cable, connect the probes and sensors, calibrate the pH probe with the included solutions, and configure the system through Apex Fusion. Label outlets carefully, test alarms, verify sensor placement, and confirm all emergency programming before depending on automation for livestock protection.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003eApex Pro Base Unit\u003cbr\u003eEnergy Bar 832\u003cbr\u003e6 ft Aquabus Cable\u003cbr\u003eLab Grade Double Junction pH Probe\u003cbr\u003eLab Grade Double Junction ORP Probe\u003cbr\u003eTemperature Probe\u003cbr\u003eOptical Leak Sensor\u003cbr\u003e15\" Liquid Level Sensor\u003cbr\u003epH calibration solutions\u003c\/p\u003e","brand":"Neptune","offers":[{"title":"Default Title","offer_id":52565595455770,"sku":"100089347","price":1379.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2259\/5719\/files\/NeptuneA3PROSystem1.jpg?v=1786565613","url":"https:\/\/piscespets.com\/products\/nep-apex-system-a3-pro-100089347","provider":"Pisces Pet Emporium","version":"1.0","type":"link"}
