It includes the Apex A3 base unit, Energy Bar 832, pH monitoring, temperature monitoring, leak detection, a magnetic optical sensor, and expandable accessory ports. For hobbyists running heaters, return pumps, skimmers, dosing systems, refugium lights, alarms, or emergency shutoff routines, the Apex A3 provides the foundation for a smarter and more protected aquarium.\u003c\/p\u003e\n\u003cp\u003eUnlike a simple monitor, the Apex A3 can control connected equipment based on schedules, sensor readings, alarms, and custom programming. That means the system can do more than report a problem; it can also help respond by shutting off a pump, disabling a skimmer, turning on a fan, sounding an alarm, or sending a notification through Apex Fusion depending on how the system is configured.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eNeptune Apex A3 Features\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eFull aquarium monitoring and control:\u003c\/strong\u003e Monitor key aquarium conditions while controlling compatible equipment through the included Energy Bar 832 and Apex programming.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTemperature monitoring included: \u003c\/strong\u003eThe included temperature probe helps track system temperature trends and can be used to control heaters, chillers, fans, alarms, and emergency actions.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLab-grade double-junction pH probe included:\u003c\/strong\u003e Continuous pH monitoring helps reef keepers track day-night swings, dosing effects, kalkwasser use, calcium reactor behaviour, and unexpected chemistry changes.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eEnergy Bar 832 included: \u003c\/strong\u003eThe included Energy Bar provides eight controllable 120V AC outlets, three 1LINK ports, two DC24 accessory outputs, individual outlet status LEDs, and per-outlet power monitoring.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePower monitoring for connected equipment: \u003c\/strong\u003eMonitor power use on Energy Bar outlets to help identify abnormal equipment behaviour, such as a pump drawing no power when commanded on or a device using more power than expected.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMagnetic optical sensor included: \u003c\/strong\u003eThe included magnetic optical sensor can detect whether water is above or below the sensor position, making it useful for sump levels, ATO logic, reservoir protection, overflow alarms, or custom water-level routines.\u003cbr\u003eSolid-surface leak detection included: The included leak sensor can alert when water is detected where it should not be, helping protect floors, stands, cabinetry, and nearby equipment.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThree built-in FMM ports: \u003c\/strong\u003eThe A3 includes three FMM accessory ports for compatible Neptune sensors and fluid-monitoring accessories.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWi-Fi and wired Ethernet: \u003c\/strong\u003eConnect the Apex A3 to Apex Fusion over Wi-Fi or use hard-wired Ethernet where a physical network connection is preferred.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eApex Fusion cloud access: \u003c\/strong\u003eApex Fusion allows monitoring, control, alerts, programming, and system access from compatible phones, tablets, and web browsers.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eExpandable Apex ecosystem:\u003c\/strong\u003e The A3 can grow with additional Neptune modules and accessories such as Trident, DOS, ATK, flow monitoring, leak detection, probe modules, lighting accessories, and other Apex-ready equipment.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003eApex A3 Controller Specifications\u003c\/span\u003e\u003cbr\u003eController model: Neptune Apex A3 Aquarium Controller\u003cbr\u003eMonitoring included: Temperature and pH\u003cbr\u003eIncluded leak sensor: Solid-surface leak detection sensor\u003cbr\u003eIncluded water-level sensor: Magnetic optical sensor\u003cbr\u003eFMM accessory ports: 3 built-in FMM input ports\u003cbr\u003eControllable AC outlets: 8 outlets through the included Energy Bar 832\u003cbr\u003e1LINK outputs: 3 outputs through the included Energy Bar 832\u003cbr\u003eDC24 accessory outputs: 2 switchable DC24 outputs through the included Energy Bar 832\u003cbr\u003eDigital inputs: 6 digital inputs for compatible switch and breakout-box applications\u003cbr\u003eNetwork connection: Wi-Fi or hard-wired Ethernet\u003cbr\u003eAudible alarm: Built-in alarm buzzer\u003cbr\u003eExpansion: Compatible with Apex A3 Series modules and accessories\u003cbr\u003eDisplay module: Sold separately\u003cbr\u003eEnergy Bar 832 Power Control\u003cbr\u003e\u003cbr\u003eThe included Energy Bar 832 is one of the major reasons to choose the Apex A3 over the Junior model. It provides switched outlet control for common aquarium equipment such as heaters, return pumps, protein skimmers, refugium lights, dosing equipment, fans, and utility pumps. Because each AC outlet has power monitoring, the Apex can be configured to alert when equipment is not behaving normally, such as a pump drawing no power while commanded on or a device using more power than expected.\u003c\/p\u003e\n\u003cp\u003eThe Energy Bar 832 also includes three 1LINK ports for compatible Neptune devices and two switchable DC24 accessory ports for supported 24V accessories. This gives the A3 a strong foundation for clean controller-board layouts, reduced power-brick clutter, and more integrated Apex automation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAquarium Use and Compatibility Notes\u003c\/strong\u003e\u003cbr\u003eThe Apex A3 is well suited for reef tanks, mixed reefs, fish-only marine systems, larger freshwater displays, and any aquarium where the owner wants more protection than individual standalone devices can provide. It is especially useful for automating heater redundancy, temperature alarms, pH monitoring, skimmer delay after feeding, return-pump shutdown during maintenance, ATO protection, leak alerts, and remote status checks.\u003c\/p\u003e\n\u003cp\u003eThe display module is not included with the Apex A3 and is available separately. ORP and salinity monitoring can be added with compatible probes and modules where supported, but the included package is focused on temperature, pH, leak detection, water-level sensing, and Energy Bar control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSetup and Installation Directions\u003c\/strong\u003e\u003cbr\u003eMount the Apex base unit and Energy Bar in a dry, well-ventilated location away from splashes, salt creep, and high humidity. Create drip loops on all cables, keep probe cables away from high-voltage cords where practical, and place probes in a stable high-flow area such as the sump. Connect the Energy Bar to the Apex with the Aquabus cable, connect the included probes and sensors, then follow the Apex Fusion setup process to connect the system, configure outlets, name equipment, calibrate probes, and set alerts. Test every alarm and control routine before relying on it 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\u003eA3 Apex Base Unit\u003cbr\u003eEnergy Bar 832\u003cbr\u003e6 ft Aquabus Cable\u003cbr\u003eLab Grade Double Junction pH Probe\u003cbr\u003eTemperature Probe\u003cbr\u003eSolid-Surface Leak Detection Probe\u003cbr\u003eMagnetic Optical Sensor\u003cbr\u003epH calibration solutions\u003cbr\u003e\u003c\/p\u003e","brand":"Neptune","offers":[{"title":"Default Title","offer_id":52565595717914,"sku":"100095832","price":934.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2259\/5719\/files\/NeptuneA3System1.png?v=1786564328","url":"https:\/\/piscespets.com\/products\/nep-apex-aquarium-controller-100095832","provider":"Pisces Pet Emporium","version":"1.0","type":"link"}
