Monitor vital water parameters to maintain ideal aquarium water quality. Neptune Systems AquaController Apex Probes provide vital data to support Neptune Systems AquaController Apex system control functions. Use Neptune Systems AquaController Apex System Probes to replace worn probes or to expand functionality of your Apex Jr Kit, Apex Lite Kit, or Apex Kit. Use additional Probes to measure and monitor water parameters of multiple aquariums or different areas of your setup.

The AquaController Apex system uses various probes to monitor your system. The measurements from these probes can be displayed on the Apex Display Module and Web Interface. The measurements from these probes can be used to control your system and alert you of problems through email alerts or audible alarms.
Temperature Probe Setup
The Base AquaController Apex Module temperature probe will be identified as "Temp", the probe on the PX1000 Probe Expansion as "TempA", "TempB" and so on, and probes on Apex Probe Modules (PM1, PM2, etc) as "TmpX3", "TmpX4" and so on. The temperature probes are connected to the port labeled "Temp" on the base or expansion module. Simply push the probe cable plug into the port until the plug clicks into place. To remove the plug, push down on the tab and gently pull the plug out of the port.
WARNING: Do not remove the rubber cap from the tip of the temperature probe or damage to the probe will occur. All probes should be rinsed in clean tap water before placing in the aquarium. Place the temperature probe in an area with high flow that is continuously wet (not an overflow that may drain dry, for example). Maintain a drip loop in the wire back to the Apex module.
Temperature Probe Calibration
To calibrate a Temperature probe: Apex Display: Setup - Temp Setup - Temp Calibrate - If you have more than one Temperature probe enabled on your system, use the up/down arrow keys to choose the probe you wish to calibrate, press Select, then use the up/down arrow keys to select the correct probe temperature, press Select when done.
Temperature Probe Maintenance
pH Probe Setup
Remove the cap from the pH probe and discard the solution in the cap. All new probes should be rinsed in clean tap water before placing in the aquarium. Place the pH probe in an area with high flow that is continuously wet (not an overflow that may drain dry, for example). Maintain a drip loop in the wire back to the Apex Base or Probe Module.
WARNING: Neptune Systems do not recommend fully submerging the pH probe as this will cause the probe to fail prematurely.
NOTE: Do not let the tip of the pH probe dry out as damage to the probe will result. If you are not using your pH probe for an extended period of time, make sure the tip is submerged in Probe Storage solution at all times. If storage solution is not available, tap water can be used (RODI water should not be used).
pH Probe Calibration
NOTE: If you wish to use the automatic temperature compensation feature, you should enable it before calibrating your pH probes. In this case, it is important for the calibration solution to be at the same temperature as the temperature probe at calibration time. The Apex system uses a 2-point calibration system, which results in very accurate readings between the 2 points and less accurate readings outside the points.
Choose the calibration solutions based on the range of pH the probe is expected to read. See the table below for recommended calibration solutions:
Recommended Calibration Solutions
NOTE: For best results, use pH calibration solutions in packets as the solution in bottles tend to shift pH after they have been opened.
To calibrate a pH probe:
If the calibration measurements were not accurate or were out of range, the calibration may fail, which will be indicated on the Apex Display. In this case, the default calibration settings will be used. You can attempt the calibration procedure again; however, this usually indicates that the pH probe is too far out of range and should be replaced.
pH Probe Maintenance
ORP Probe Setup
The ORP probe is connected to the port labeled "pH/ORP" on the Apex Base Module and Probe Module 1. Push the BNC female connector on to the male connector and turn ¼ turn clockwise to lock the connector place. To remove the probe, turn 1/4 turn counterclockwise and gently pull the connector straight off the base module. All new probes should be rinsed in clean tap water before placing in the aquarium. Place the ORP probe in an area with high flow that is continuously wet (not an overflow that may drain dry, for example). Maintain a drip loop in the wire back to the Apex Base or Probe Module.
NOTE: New ORP probes typically read low and require a break-in period. It may take as long as a week to break-in the ORP probe. During this break-in period, control functions based upon ORP are not recommended.
WARNING: Neptune Systems do not recommend fully submerging the ORP probe as this will cause the probe to fail prematurely.
