      5. Start monitoring and controlling your entire tank, in less than an hour, with no programming

      General Information
      Wireless Internet-Ready!
      For years Neptune advocated a wired network connection for your Apex due to its superior reliability - and they still do. However, for many people a wired connection is just not possible.

      So, for this Apex Neptune spent countless man-hours developing an incredible 802.11g/n Wi-Fi connection with reliability that rivals a wired connection. And, the connection process to your home network is amazingly simple, getting you set up and on the Apex Fusion cloud service in just a couple of minutes!

      IoTa - (Internet of Things, Aquarium)
      The Apex is an IoTa platform built for reliability when things go wrong - not just a toy to play with everything is A-OK.

      Every Apex has a built in web-server (tech talk for its control panel) with complete functionality - even if the Internet is down! This is important, see why . . .

      Let's say you have a power outage and want your aquarium to take the appropriate actions to maintain the fish and corals for the longest time possible. Or, what if the Internet is down (or a company's cloud servers) and you simply want to manually turn on your lights or turn off your skimmer.

      Some aquarium controllers work ONLY via their online cloud service, so when the Internet is down or slow, you are out of luck. With the Apex you can continue running your tank without interruption.

      Energy Bar 832 (EB831) - The Ultimate Power Control Hub
      This Energy Bar 832 was redesigned from the ground up. Not only does it have eight 120V AC outlets, but it includes an internal 100W 24VDC power supply as well. That power supply feeds three built-in 1LINK ports as well as two 24VDC accessory ports. Each individual outlet has power monitoring and there are individual LED indicators for each outlet.

      Energy Bar 832 Specifications

      • (13) Total power connections for your aquarium devices
      • (8) 120V AC Outlets all switched with relays rated for millions of cycles
      • (3) 1LINK 24VDC Smart outlets for devices such as WAV, DOS, etc.
      • (2) Switchable 24VDC outlets for accessories such as small pumps, solenoids, fans, etc.

      Power Monitoring
      For years Neptune has been asked to do the power monitoring of the individual devices connected to each outlet – but it just wasn't possible without breaking your bank. Now it's here and with comes tons of benefits.

      For many, the cost of the electricity to run a successful aquarium is a major concern in their household. Even for those where electricity is cheap, Neptune believes most aquarists care a great deal about their energy consumption and its effect on the environment. Ironically, our energy usage could be directly connected to excess greenhouse gasses, the warming of the oceans, and the bleaching of the corals!

      However, armed with the right information Neptune believes aquarists will not only be able to make operating and purchase decisions that will save them hundreds of dollars a year, but they will also be able to reduce their carbon footprint.

      Built-In 1LINK and 24VDC Ports
      This Energy Bar has a built-in 100W, 24VDC power supply that can control up to three Neptune Systems 1LINK products like the WAV and DOS. It also includes two switchable 24V DC on/off outlets that are compatible with any 24V device under 30W and Neptune Systems 24V accessories like our Practical Multi-purpose Utility Pump (PMUP).

      Individual Outlet Indicator LED
      Each Energy Bar AC outlet, as well as the two 24VDC accessory ports, has their own status LED. This LED tells you when that outlet is energized. The LED will also blink rapidly if a device is plugged in that exceeds the current capability for that outlet.

      Alarms and Decisions Based on Power
      Since the Apex is receiving continual power usage data from the Energy Bar 832, it can be configured to send you notifications when a device is not using power as it should. An example would be a return pump showing no power consumption when the outlet is on or a skimmer whose power consumption will show differently when its airline is clogged when compared to normal operation. These high and low limits are completed customizable by individual outlet. You can even use this power data to control other devices.

      All Outlets Relay Switched
      Times have changed and it is fairly uncommon now for aquariums to have AC devices that must be cycled on and off continuously. This means that Neptune could now switch all AC outlets to relay switching since there is no need to have soft start and there is no concern for the noise of the relay.

      New Mounting System for Both Apex and Energy Bar 832
      Both the Apex and the Energy Bar 832 have an innovative attachment system that makes it easy to mount them up and also give convenient access to all the connections. The Apex mounts with just two screws. It has a hinged mount where you can flip it up, make your connections, and then flip it down, making it more difficult for water to enter the electronics via a cable. The Energy Bar 832 has a mounting bracket you screw to the wall with just three screws and then the Energy Bar slides down onto the bracket.

      Probes Included with your Apex System to Monitor the Health of your Aquarium
      The Apex System includes probes for Temperature, pH, ORP, and Salinity. The pH and ORP probes are now double-junction as well so they hold calibration longer and have a longer lifespan than single-junction probes.

      What's the difference between double junction and single junction probes?
      Single junction probes put the reference electrode in direct contact with aquarium water. Over time, the junction will slowly leak aquarium water into the electrolyte, which changes the accuracy of the probe and requires more frequent calibrations.

      Double junction probes place a second vessel inside the main electrolyte with a second internal junction. This means that even when the aquarium water eventually begins to make its way in the first compartment, it still has to go through the second junction to contaminate the electrolyte surrounding the reference electrode.
