I use the Apex to turn various pieces of gear on and off, to get alerts when certain items are out of range, and to track water parameters. 

For the last decade, I've been using Neptune System's Aquacontroller.  First I had the AC II, then later upgraded to the AC 3.  Near the end of 2011, I gifted myself the Apex controller, the latest available version at that time.  The Apex has been around for a couple of years, and many of my friends swear by it.  

The controller turns the lights on and off, as well as the heaters and fans (or chiller, if you have one).  If the tank runs too hot, the controller can shut off the lights to stop adding further heat to the water.  And if it has been set up with a battery backup, it can notify you via text or email if the power goes out.  

When the Aquanotes App came to market, I instantly bought an iPhone so I could stay in touch with my tank when traveling.  It allowed me to check on the system, and I could call a friend if there was a major issue.  I didn't have it programmed for more than what I considered the essentials.  I used x-10 modules to control the various lights and heaters, letting the AC3 act as the timer for each piece of gear.  Over time, the x-10 modules became flakey, not working consistently which was very frustrating.

 

 

The upgrade from the AC3 to the Apex was a big jump forward.  I bought the base model, two Power Bar-8s (PB-8) and one Power Bar-4 (PB-4).  I bought an extra 12v power supply for the UPS, used in a power outage to keep the Apex on for communication to my router.  Also, I ordered a 15' extension USB cable, because 15' + 6' was just enough wire between the EB-8 and the Controller module itself.  This time, all my gear would work like it should.

I have Cat5 cable running from my router through the attic to the fishroom, as I didn't want to use a wireless bridge.  To me, that's just one more point of failure, especially in an emergency.  The router is plugged into a UPS, so if the power goes out, the Apex and the Router are still running and I'm able to receive texts and emails being sent to me.  If I'm home and one of the pre-programmed parameters is out of range, or if a PB detects a power outage, the display plays an alert chime to get my attention. I've only heard it when the probes were exposed to air or when I unplugged something intentionally.

 

The (2012) Apex App is much nicer than the previous Aquanotes App.  And once I updated the firmware in the controller, the latest version of the App allows me to make changes to the programming right from my phone no matter where I am.  The new graphs are easy to access, faster than previously, and I can zoom in and out the the flick of a finger.

And now we have Apex Fusion (2014) that is cloud based.  It makes connectivity easier, and you can turn this on and off from any device that uses a browser. I had to update the firmware, create an Apex Fusion login account, and then enable it via the Apex Dashboard.  The rest of it kind of just worked without any fuss.

 

 

The PB-4 is used to run the heaters as they draw 300w each.  The PB-4 is plugged into its own circuit.  Three heaters are plugged into the power bar, with room for one more if need be.  

The lower PB-8 is used to run these items:  Refugium LED lighting, Frag tank LED lighting (whites and blues), Icecap 120mm Cooling Fan, the Skimmer Swabbie, with room for a few more items. The upper PB-8 runs all the lights: 250w Metal Halide, 400w Metal Halide, 250w Metal Halide, VHO actinics, and LED moonlighting, with room to add more if necessary.

The PBs use USB cables (supplied) to connect one another, with one cable connected to the controller (or brain).  The Display Module can plug into the brain, or to any of the PBs.   All the PBs are securely mounted in areas where they should stay dry and safe from splashing.

I don't use the Apex to control my calcium reactor nor the Vortech pumps.  I'm not dosing anything, yet. But what it does for me now, it does perfectly and I'm very pleased.  

 

Below are three more screenshots from the Apex App, released in the first quarter of 2012:

    

Here's a screenshot of Apex Fusion on my desktop.  It's a nice scrollable screen on my iPhone, if I want to access it that way.

 

Check out the new graphs, which you can scale to show you a few hours or a few days at a time.  It displays the past 24 hours in the big wave, and the past 7 days in the smaller pattern.
