Apex Lite System

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

Built-in Ethernet

Integrated Ethernet port
Most advanced web server available
Interactive flash 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
Interactive flash graphing application in the web server

Very simple menu driven configuration

Menus to easily setup pumps, lights, heater, chiller, co2, etc
No programming required for configuration
Can name the outlets (unlike competing products)
Can be configured through LCD Display or a standard web browser
In advanced mode an enhanced AquaController programming language is available
Sophisticated non standard control available
Virtual Outlets allow even more complex control options

Monitor/Control - pH, Temp

The base unit includes software which is capable of monitoring pH, and temperature. The monitored data is continuously displayed on the large LCD display and also logged into the internal nonvolatile memory for later retrieval. All probes support digital calibration.

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
The huge code space means that future expandability is ensured
Over 16 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 either have a random or fixed time period. Both the on and off times are fully programmable and can range from 1 minute to 4 hours in 1 minute increments. Four independent variable length feed timer cycle scan be initiated with the press of a button and will disable some or all of the pumps in the system (programmed by the user).

6 Digital Inputs

The Apex comes equipped with 6TTL level external inputs which can be used to activate/deactivate equipment in response to an external stimulus. Applications for these inputs include connection to water level float switches, water pressure and flow sensors, and water on the floor sensors. The Apex can be configured to signal alarms or turn on/off appliances in the event of external switch open or closure.

Modular Expansion through AquaBus

High reliability protocol with robust error correction
Virtual unlimited expandability. The most expandable controller.
Plug and Play – AquaBus modules are automatically recognized and configured
Cable lengths over 200 feet
Expandable to 240 AquaBus modules
Add optional modules to monitor Hundreds of Probes
Add additional EnergyBars to control thousands of outlets
All AquaBus modules allow for easy firmware updates
Probe modules available (or in development) for additional Temperature, pH, ORP, Conductivity, and dissolved oxygen probes
Module firmware updates done through AquaBus. No need to disassemble controller, and individually update modules

Backward Compatibility

All AquaController 3 accessories work with the AquaController Apex. One major design consideration was to maintain backwards compatibility to protect existing customer’s investment in AquaController compatible equipment.

o I/O port expansion backwards compatible with PX 1000
o Compatible with the breakout box
o Integrated control port - All control port accessories (DC8, DC4, DC4HD, AquaSurf, Lunar Sim)

AquaBus Features

Two AquaBus connectors for easy expansion, and flexible cabling options
Plug and Plug bus allows for modular expansion.

Updateable Firmware

Firmware updates via Ethernet
Flash memory so new features can be easily added
All AquaBus modules allow for easy firmware updates
No need to unplug/rewire devices to perform the firmware update (unlike the competition)

Alternate power port on Apex Lite Base Unit

In power failure situations Alarm emails can still be sent
Can detect power failures in EnergyBars
Internal rechargeable backup battery retains clock
Graph probe/device data on the LCD display
