Product Questions

Is there any other equipment needed (purchase) to measure PAR?
Question by: Maurice Thomas on Apr 24, 2016 2:13:00 PM
Great question!
The Seneye will include all components for measuring PAR.
Answer by: Connor (Admin) on Apr 27, 2016 11:46:00 AM
Does the Seneye ever need to be re-calibrated for things like PH or Ammonia? Is there a shelf life for the Seneye?
Question by: Jonathon Smith on Jan 14, 2016 1:48:00 PM
Great question!
The System will need to be re-calibrated for the pH and Ammonia. this can be done during the monthly slide change. There is not a shelf life however the slides will only last 1 month in the aquarium. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 14, 2016 5:24:00 PM
I have heard there is an additional $60 fee to measure PAR. Is this true?
Question by: Steven Bidny on Jun 4, 2016 10:34:00 PM
Great question!
There is no additional fee to measure PAR and it is built into the module itself.
Answer by: Connor (Admin) on Jun 9, 2016 2:32:00 PM
Will the light meter, temperature sensor, and water level sensor continue to function without purchasing new slides?
Question by: Steven Bidny on Jun 4, 2016 10:35:00 PM
They certainly will! Only the ammonia and pH will need refill with the disks.
Answer by: Connor (Admin) on Jun 9, 2016 2:33:00 PM
Does the device need to be connected to the Internet (via a PC or SWS) in order to measure PAR? Or can it store the data locally for later upload? If so, will it only measure once an hour?
Question by: Steven Bidny on Jun 4, 2016 10:40:00 PM
Great question!
When plugged into a PC it will be able to monitor and read PAR levels every 10 minutes, Same with the web server. The levels will be kept and stored for viewing previous PAR levels.
Answer by: Connor (Admin) on Jun 9, 2016 2:34:00 PM
I have heard the device requires access to the Seneye cloud to process PUR and spectrum readings? Is this true? Is it only able to capture PAR and lux as a stand alone device?
Question by: Steven Bidny on Jun 4, 2016 10:46:00 PM
The dashboard display on the PC will work well even without the Could or server. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jun 9, 2016 2:37:00 PM
How many slides on initial package
Question by: Carlos on Mar 22, 2016 12:56:00 AM
Great question!
There will be one included slide with the kit. It is a great idea to have replacement slides on hand for replacement in the coming months. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 22, 2016 10:52:00 AM
Can I plug this gadget into an xbox one?
Question by: Jamie Springer on Jun 7, 2016 7:37:00 PM
Great question!
We are not aware of any way for the software to connect unfortunately. Feel free to let us know if you have any further questions.
Answer by: Connor (Admin) on Jun 8, 2016 6:04:00 PM
How does this monitor measures light? Do I have to place it where I want it to take the reading?
Question by: Emmanuel Becerra on Mar 23, 2016 1:00:00 AM
Great question!
This will use a LUX meter similar to a PAR meter and can be moved around the tank to find the correct readings if needed. This is actually an ideal measurement device for LED lights. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 23, 2016 10:49:00 AM
I is this device compatible with iOS devices such as my macbook air?
Question by: Adam Lawless on Jan 20, 2016 1:24:00 AM
Great question!
This is not compatible with Mac or iOS however if you purchase the kit with the web server you can access the information through any browser. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 27, 2016 3:45:00 PM
Can I limit the amount of time this is in the tank to make the cards last longer? for example if I use it for a hour several times a week would the card possibly last for a year?
Question by: Charles Lewis on Feb 26, 2016 10:48:00 AM
Great question!
Unfortunately there is not a good way to save the discs after placing in the tank. They will lose performance if removed and dried regardless of drying or storage. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 26, 2016 11:23:00 AM
Dos the par meter work with reading hqi lighting i seen u say led's its designed for? What brand of duble ended hqi bulbs do u think are top of line in the hobby
Question by: matthew on Mar 24, 2016 4:26:00 PM
Great question!
The seneye is able to monitor all types of light evenly! For double ended bulbs we have had great luck with the phoenix and Giesemann. I have included a link below!
Answer by: Connor (Admin) on Mar 24, 2016 4:38:00 PM
Am I reading this correctly, the seneye reef will only take a PAR reading every 10 minutes? You cannot move the sensor around and see PAR in real time, like with the apogee?
Question by: Sean Kehoe on Nov 11, 2016 4:00:00 PM
Hey Sean,
The Seneye will record a par measurement every so often, it does also give you live readings as well. You can take multiple measurements around the tank at one time.
Answer by: Jason Smith (Admin) on Nov 14, 2016 10:43:00 AM
To measure PAR, will I need a PC as well? Or can I measure PAR with just the unit itself or by connecting to a Mac?
Question by: Chuck on May 16, 2016 10:16:00 PM
Great question! You will need a PC in order to use the Seneye as it is not MAC compatible.
Answer by: Carter (Admin) on May 24, 2016 11:30:00 AM
What is the accuracy of the temperature reading?
Question by: John on Nov 21, 2016 10:05:00 AM
Great question! The temperature variance will be +/- 2 degrees. :-)
Answer by: Randy (Admin) on Nov 21, 2016 1:11:00 PM
Does it come with the power adapter, and slides?
Question by: Addison Henderson on Jul 10, 2016 5:02:00 PM
Hi there,
The Reef Monitor does come with one slide. It is powered through USB that can be powered through any USB port. It does not come with a 120v or 12v power adapter, but they can be purchased separately.

Full Details

Owners Manual


What does it do?


Constantly monitors water temperature, so you can get an alert if your heater breaks or your chiller fails

Free Ammonia
Monitors the highly toxic free ammonia (NH3) at very low levels, so you can stop your fish from dying from Ammonia posioning.

The seneye monitors pH in your aquarium or pond water between 6.4 and 9. This range is ideal for most aquatic life and by focusing on this range increased accuracy has be achieved.

Water Level
Readings are only taken when the seneye device is in water, no false readings.

Monitors ambient LUX and can be used to take direct LUX readings, understand how your light degrade over time.

Understand where on the kelvin range your lights are and how light can change over time.

Monitor the Photosynthetically Active Radiation (PAR), understand if you have the correct quanity and quality of light for your corals or plants.

  • This this is junk By chance on 9/14/2016

    This thing is a joke I tried customer service- there was none, tech support-none, someone to answer their phone even at the seneye company even no and hell no! I'm sorry but this left a very bad taste in my mouth after the purchase of this and the wifi box as well which cost well over $400 at the time I'm sorry but This is not right at all to spend this kind of money for basically a constant ph meter, ammonia and temperature readings and water level sensor that you can check all on from your smart phone through the app and have alerts sent to you in texts which when it works is great!i would have given it a zero but it won't let me so there ya go
  • WOW! By Giancarl on 9/14/2016

    I saw this product at macna and i love it!
    PAR is on the spot and PUR is a great addition!!!!
  • QT Ammonia Feature all I wanted By Drew on 9/12/2016

    Really a big fan of active medicated large QT tanks and Ammonia is always a concern. Since I switched to this with active Ammonia Monitoring, using buffer PRO salt mix, ordering only through favorite store through Quality Marine, and using Quinone Sulfate through vet everything lives!!!!
  • Excellent piece of gear to compliment my controller By DeepBlue45 on 6/30/2016

    I purchased the Seneye because I run a ReefKeeper Elite controller but don't have it connected to internet. With the total amount I have invested in fish/corals I like that this gives me a back-up pH/temp monitor plus ammonia monitoring with alarms over internet via the wifi module. Also, running only LEDs I think the PAR meter is almost mandatory. I ran into a few challenges during set-up but otherwise functioning smoothly now and low maintenance.
  • WORTH IT FOR THE PAR METER By DavidC on 6/29/2016

    I bought this after BRS reviewed the Seneye and affirmed it's accuracy.
    I did not want to spend $300 or more for a PAR meter. If you're wondering why the price for the Seneye PAR meter is much less, I presume it's due to the fact that you connect the meter to your own PC to monitor PAR, rather than with a hand held monitor.
    Anyway i was really wondering what my PAR levels were in my 38 gallon Nano. The results were a real eye opener. It turned out the Seneye indicated that my PAR levels were very low. Even near the top of the tank, direcly under the lighting, the PAR barely reached 400. I had had my Radion at about 40% intensity. I now have them at 66% and all my corals, including SPS, are doing fine.
    I will say that the temp & PH readings are definitely off. However, I bought this solely to measure PAR and I am happy with this purchase.
  • Seneye Reef monitor By Cleveland on 5/3/2016

    Works great!
  • Only works for Ammonia By tab1129 on 3/27/2016

    This thing is amazingly accurate at measuring ammonia levels. I work in a lab and have verified its accuracy with pre-made ammonia samples. However, as a pH meter and a PAR meter it is not very accurate at all. This is disappointing because if you have a stable reef monitoring ammonia is not that important while pH and PAR are very important.
  • Pretty good By LouS on 3/18/2016

    Tried using on Mac with boot camp and win7 but software did not like this combo. Switched to my win 7 hp and worked better but kept giving errors during install. The errors did not effect final operation. The software definitely needs some refinement but works well once it's up and running. Keep in mind that the device needs to be hooked up to a computer all the time or to a usb power source in order to log parameters. It will take a little while to stabilize once it's connected. If you can do it the web server is a must have and the slides are a little pricey. Regardless I like this product very much.
  • Good product with a bad suction cup By Kurt on 2/12/2016

    Unit is working as expected but I can't get the suction cup to stick to anything. They even sent me a new cup and that does not stick either.
  • Stopped functioning after 2 weeks By Michael on 1/22/2016

    Purchased the Seneye Reef Monitor and used it for 2 weeks before the ph and nh2 alert lights came on and it started reporting 0 for both. I assumed that i had somehow damaged the slide so i paid $30 to purchase a new one(they force you to buy 3 at once). After soaking and installing/activating the new slide the device continued not to give reading for ph and nh3 and read 0 for both. After troubleshooting with seneye technical support they concluded that the device was faulty. Anyways, a product that costs $200 should function for more than 2 weeks and now i'm out the cost of the new slides unless i want to get another unit. Don't buy this unless its just for the par meter.
  • Great Alternative to Monitoring Water Parameters By Thinner on 1/2/2016

    I purchased this for the sole purpose of monitoring free ammonia and ph in my newly set up 55 gallon reef tank. It does monitor temperature as well but I have my RKL (basic) to do that for me. The great thing about this is that it monitors free ammonia down to .000 ppm. This has saved me a couple of times already when I saw my ammonia creep up from .001 to .003 to .010..which in theory is still safe levels. Nevertheless it enabled me to react quickly and performed a water change and saw my reading went back to .001 ppm.

    I do agree wth the reviewer who mentioned that this is not for mature tanks since free ammonia levels should not be an issue already.

    One great thing about this is that I do not have to calibrate pH however it comes with a price. Slides needs to be purchased every 30 days. (About $10 per month).

    I am hoping though that Seneye will come up with other water readings such as Nitrites/Nitrates.

    As of the moment, this devise works well for my purpose.
  • Works well, but..... By marion on 11/9/2015

    This product works as advertised but most mature tanks have stable PH, ammonia, and temp so this product is really for new tank owners. I actually bought it for the par meter not the other functions and at $10/month to buy another slide, those functions just aren't worth it for me. I think it would be good for a QT tank though so if the $10 for the month to help monitor the QT is probably worth it but not for DT. Now f they come up with a slide that measures Mg, Ca, and would be a no brainer.
