FAQ

My controller will not connect to the PC software
    • Make sure that your PC interface is properly connected (see instructions)
    • Check that your Controller is on the main screen (where the date and time can be seen)
    • If you are using the serial/USB (ACQ221) adapter, make sure to install the drivers on your PC (CD found inside the box)
    • If you are using the serial/USB (ACQ221) adapter, check that the yellow LED flashes.
    • Check that the COM port that is set on the Aquatronica software (settings-communication port) corresponds to your PC’s port

 

My Density probe (old unit with code no.ACQ310-D) is not reading a correct value.
    • Have you calibrated the probe?
    • Check that your probe isn’t in an area where air bubbles form. Air bubbles can accumulate inside the probe’s sleeve and cause incorrect readings.
    • If the probe has been in your aquarium for more than a month remove the sleeve and check the electrodes for algae, use a clean cloth and wipe it. The probe should be placed in an area with some water movement.
    • Check the electrodes for rust. Some probes tend to form rust after a few weeks operation. After various tests we have verified that if this rust is removed, the electrode continues to function properly. If your probe continues to rust, contact your distributor for a replacement. We are currently working on a solution for this problem.

 

The readings from the density probe (new unit with code no. ACQ310N-D) do not agree with the readings taken with a refractometer or densitometer.
    • See the article entitled, “Measuring the Quantity of Salt in a Salt Water Aquarium” available in the Literature area.

 

My pH probe will not calibrate.
    • Verify that you have connected the correct probe to the interface (pH should be written on the probe).
    • Check that you have used the correct calibration solution. The calibration value must correspond to the calibration fluid.
    • While in calibration mode, wait until the probe stabilizes on a value, or starts fluctuating between two values. If the probe reads a value that is very different from the set value, it may not calibrate.
    • Do not leave the controller in calibration mode too long. We recommend leaving the controller in this mode for no more than 30 minutes.
    • If you’ve had the probe for more than 12 months, your probe made need to be exchanged for a new one. Our probes have a lifespan of roughly 12-18 months, depending on use and maintenance performed on the probe.


Does the Redox probe need to be calibrated?
    • Just like the pH probe, the Redox probe must be calibrated to obtain reliable results.

 

The protective cap on the Redox/pH probe I've just purchased does not contain liquid, and salt crystals can be seen on the probe. Is the probe still good?
    • No. The liquid normally contained in the protective cap is a saline solution that is used to keep the electrode hydrated. When the liquid dries, it forms salt crystals that deposit onto the probe, but this does not indicate a malfunction. Simply immerse the probe in the aquarium for at least 48 hours to rehydrate it adequately and then proceed with calibration.

 

How do I calibrate my temperature probe? Does it even need to be calibrated?
    • The temperature sensor is given a standard calibration at the factory and does not need further calibration. In any case, it can be calibrated to correspond to the other temperature sensors in the aquarium if comparable results are desired. Simply set the temperature value measured by the other sensor as the reference temperature.

 

How many Power units and sensors can I connect to a single system?
    • The limit is 10 Power units and 20 sensors.

 

What is the maximum length that I can run a USB cable from one PU to another?
    • We have tested up to 15 meters. You can try even longer but the connection could become unreliable.
 

Can I connect other types of probes into the interface?
    • In some cases yes, if you have a pH or Redox probe which has a BNC connector, it may give a correct reading but the system may not be able to calibrate it. Of course we cannot guarantee that all probes will be compatible.
 

I cannot do an internet update.
    • First of all, make sure that your computer is connected to the internet.
    • Verify that there is no firewall, or anti virus active on your computer that is blocking the connection. This is how you create an exception for our software on Windows XP with Service Pack 2:
    • Enter Control Panel -Windows Firewall
    • Exception -Add program
    • At this point you will have to find your aquatronica program, usually found in C:Programs-aquatronica-aquarium controller-then find ONLINEUPDATE.EXE.
    • Make sure the checkmark on the side is on. Try connecting to our site.

 

I was doing a controller update and my controller got blocked during the firmware update.
If your screen goes black and you are unable to connect to the system using the software try following this procedure:

    • unplug your controller from the Power units for 10-15 seconds then re-connect;
    • close and re-open the Aquatronica software;
    • go into FILE and select CONTROLLER UPDATE, do NOT press the CONNECT button;
    • the software will begin the update procedure and should automatically connect the controller
    • the system will ask you to select a language, then it will complete the download.

Unfortunately, by doing this procedure you will lose your programs so always save your configurations before doing an update. This procedure usually works even if the firmware update is blocked at 1%.


How many programs can I set on a system?
For a standard complete system (one of everything):
    • 16 Timer programs
    • 20 Sensor programs
    • 4 Wave effects
    • 4 Tide effects

The Aquarium Controller system can support a maximum of 10 Power units and 20 sensors.

I have reset my system or changed Controllers and would like to download my saved configuration, but my PU’s and sensor designations are all wrong.
If you have more than 1 PU or more than 1 type of the same sensor (e.g. 2 levels/3 Redox) we highly recommend disconnecting these sensors, reconnecting them one at a time, and giving each one of them a designation BEFORE loading a saved configuration. While the software is loading the Power unit configuration, it will ask you to verify which PU corresponds to the ones that are saved in the file. The same happens with the sensors. If the wrong PU or sensor is set, the programs will not correspond with the plugs and you could risk damaging your aquarium!

NOTE: This happens because the plug and play system will designate names to whatever it first reads. This is true for both PU’s and sensors, for this reason, if it is possible, we recommend unplugging all PU’s and sensors BEFORE resetting your system. Once you have reset, plug in one sensor at a time giving it the name you want. By doing this the system will recognize them in an orderly fashion.

Is it safe to fully submerse the probes?
 No. The seam on the cable must always be approximately 2 cm above the water.
 
 
Does one type of program override another?
Yes. The programs that can be set using Aquarium Controller have priority over the others based on the table below. The programs are listed in order of decreasing priority:
    1. Water leakage sensor program
    2. Manual commands
    3. Blackout
    4. Function key: LEFT
    5. Function key: DOWN
    6. Function key: RIGHT
    7. Function key: UP
    8. Sequences Program
    9. Level sensor program
    10. High conductivity (density) sensor program
    11. Low conductivity sensor program
    12. Temperature sensor program
    13. pH sensor program
    14. Redox sensor program
    15. Summer function
    16. Wave effect
    17. Tide effect
    18. Program timer

Programs XY have varying priorities depending on the sensors involved in the program. The priority will be one position higher than the highest of the sensors included in the variables. For example, an XY program that has pH and density as variables will have a priority falling between density and level.

Does my Density probe already compensate for temperature variation?
The Density probe has a build-in thermometer that measures the temperature and automatically compensates the salinity value. This means that if you are also using another instrument for measuring the salinity (such as a Refractometer, or a Specific Gravity Meter) and your Density probe is reading a different value, you must also keep in mind that temperature variations may not be compensated in the other device.
