Login to our Apex Controller

We have loved Neptune Systems’ controllers ever since we got our hands on our first Aqua Controller back around 2002.  With the latest Apex system, we have performed water changes from Costa Rica, been notified of leaks and temperature drops from the Dominican Republic, and now you can see how we have our Apex setup!

Neptune System’s new web based Apex Fusion is for the first time, giving us a chance to let you login to our controller and have a look at what we have going on here at ReefNation.  Hopefully this is helpful for you all to see as we have some interesting programming on our controller that we hope others might be able to take advantage of.  Shoot, maybe some of the other “control freaks”  out there have some feedback and ideas for us too which is always interesting to hear!

What does our main system look like?

We run a few different systems here at ReefNation, two of which are on Neptune Apex controllers.  One is an Apex lite and one was the full package.  The Apex lite runs our main system and has the following modules plugged into it:

-Energy Bar 8 (3)

-PM2 module  This adds our second temperature probe that tells us what temp our Sump is at

-PM1 Module ( 2)  Control our pH probes for Tank, Calcium Reactor, and Kalk Reactor

-VDM -Controls all the 0-10v dimmable Rapid LED arrays we have built

-Display Module

-Main Apex Lite- gives us first temp and pH probes

A little about our setup

Our apex controls the normal reef functions right now such as lighting , temperature, and cooling.  A few of the more complex things we have programmed it to include some if then statements such as if pH >8.40  shut off the Kalk dosing or if pH CR > 6.9 then email “replace CO2 tank on Calcium Reactor”.  If you are curious, you can look at see how many of these functions are programmed on our controller and while there are even more complex things you can do, this has maintained our tank in a rock solid way for a few years now.

If you have any questions about how we have programmed our controller, how to set something up on yours, or if you have a tip for us, we would love to hear from you at

Happy Reefkeeping!
