Neptune Apex Lite Controller
Neptune Apex Lite AquaController
Neptune Apex AquaController Lite Packages

The Neptune AquaController Apex Lite has all the fuctionality of the full Apex system except for the variable speed ports and the ORP port. The AquaController Apex has the ablity to monitor abd control temperature and PH. It includes a multiline back lit display and control interface as well as temperature probe and 8 plug energy bar. With the use of the additional optional modules offered by Neptune the AquaCotroller has the ablity to control Tunze controllable pumps, some LED kits, AquaIllumination LEDs, Ecotech wireless pumps and more.

Using an ethernet connection on your home router the Neptune AquaController Apex Lite can be accessed and setup via your PC with a web browser or IPad with the offical Apex app. Also with addtional setup can send you email alerts and even access the Neptune Apex Lite from outside your home on the web!

  • 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. Up to 20 pumps can be controlled by one base unit. 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).
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
