The Apex Jr System delivers a professional quality controller at hobbyist prices.

Built-in Ethernet

Integrated Ethernet port

Most advanced web server available

Interactive graphing application in the web server

Interfaces with AquaNotes iPhone application

Compatible with all Major web browsers (Internet Explorer, Firefox, and Safari)

Only aquarium controller with web server monitoring, control, and configuration

Compatible with wireless bridges or game adapters (802.11x) so that wireless network communication is possible

Email or text message alarms

Email alarms or audible alarms when Energy Bar power fails

RSS and XML Support
Very simple menu driven configuration

Menus to easily setup pumps, lights, heater, chiller, co2, etc

No programming required for configuration

Outlets can be renamed for easier use

Can be configured through optional LCD Display or a standard web browser

An enhanced AquaController programming language is available for total control

Sophisticated non standard control available

Virtual Outlets allow even more complex control options
Monitor/Control - Temp

The base unit includes software which is capable of monitoring temperature. The monitored data can be displayed on the optional LCD display, the Apex's web page, or through the AquaNotes iphone application. All monitored probes data is logged into the internal nonvolatile memory for later retrieval. All probes support digital calibration.

Integrated 4 Outlet Control

The base unit includes 4 independently controllable outlets. Each of the 4 outlets is rated for a total 8 amps and the total current draw must be less than 15 Amps. All 4 outlets use relays to control the power to the outlets.

Galvanic isolation on probes

Galvanic isolation on the probes results much more reliable and accurate probe readings. While these features increase costs we feel that probe accuracy is absolutely critical for monitoring/controlling your tank, unlike many competing aquarium controllers.

State of the Art Electronics Integration

Only 32 bit processor on an Aquarium controller

Over 16 times more code space & 5X faster than competitive controllers, which guarantees future expandability.

Over 8 times data storage memory than the competition

1 year’s worth of data logs can be stored internally
New Enhanced Control Functionality

Day of Week functionality

Sub minute control added on EnergyBar controlled devices

Default outlet state for all EnergyBar outlets

Second resolution control
Sunrise and Sunset Simulation

The Apex has a special control function which can be used to simulate the varying lengths of days throughout the year. This feature is used to make the length of daylight hours longer in the summer than in the winter. This results in a more realistic simulation of natural lighting variations.

Moon Cycle Simulation

The Apex has another special control function which can be used to simulate the moon cycle in your tank. The lunar simulator is used for this feature and is capable of varying the intensity of light emitted from its LEDs. The intensity variations are controlled by the Apex which is preprogrammed with correct intensity values for each day of the moon cycle. The Apex automatically updates the intensity value depending upon the current setting of the Apex's clock. With this artificial moon cycle, it is possible to induce corals and fish to spawn.


Each pump to be controlled can have an user configured period in which both the on and off times are fully programmable and can range from 1 second to 999 minutes. A variable length feed timer cycle can be initiated with the press of a button and will disable some or all of the pumps in the system (programmed by the user).
