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
is there a warranty
Question by: jerry swank on Dec 5, 2016 2:37:00 AM
Hey Jerry,
Most seneye products come with a one year limited warranty. You can check your warranty here:

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.
Answer by: Charlie (Admin) on Jul 11, 2016 10:40:00 AM
Can one unit work on multiple tanks? Or do we need to have more then one unit to monitor more then one tank?
Question by: Randy on Jan 3, 2017 1:20:00 PM
Great question! These must be submerged, in which case, you will need one monitor per tank.

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.

  • Dead before it even hit water By Jim on 4/17/2017

    I took my seneye out of the box and followed the online instructions. (Which weren't that user friendly) It started to download a new firm wear update and then the unit crashed. I mean dead as a door-nail. Customer service is overseas. So expect bad hours to get a response and when you do they don't address the issues. Stay Away!
  • Great product and good customer service By phillipt on 3/13/2017

    well worth the price , easy to use and monitors what you really need saving you from expensive test kits in the long run.
  • Waste of money By Reggie on 3/10/2017

    I bought this to get an base line of par on my reef before I upgraded my lights. I wanted to slowly increase my par over the next 6-8 weeks. The day I got it I installed and it work beautifully, I used for about 30 minutes. 2 day later I upgraded lights and it would not connect to PC. The "customer support" closes at 11 CST so if you work, they are useless. I have exchanged 20+ emails and no resolution. Keep your $200. My par level is now unknown.
  • Great monitor, if you don't already have one By Jeremy on 2/21/2017

    This is a nice little device for a number of reasons.
    - It is a low cost PAR and LUX meter. LUX for fish-only tanks, and PAR for reef or planted tanks. That alone is probably worth the cost. I just wish it had a horizontal mount, not just the suction cup to mount vertically.
    - It is the only real-time ammonia monitor. That hasn't been a life saver for me yet, but if you have the money, it helps with piece of mind.
    - The temp and pH monitoring is useless to me, since I have Apex, and it already checks all of that, and more. But if you don't have one of the other full-system controllers, this is a great alternative.Temp and pH stay fairly close to my Apex measurements. (Apex is in sump, and Seneye in the tank). And those can be adjusted, if they are off a bit.

    I'm going to continue using this. It's a great safe-guard, and redundancy is good. If they make a new one that does ammonia AND alkalinity or calcium, I will upgrade in a heartbeat!
  • Wont stay put! Par meter works. By Steven on 2/16/2017

    The suction cup mounting stinks! It wont stay on the glass. The monitoring would be nice but i dont wat to have this thing just hanging in the tank. Par meter works good with led lights. At least i can use it to check par.
  • PAR meter works great! By Ronald on 1/17/2017

    Easy to set up for PC laptop and was up and running gathering par readings in 30 minutes. Definitely a must have for deterring light levels for finicky corals!
  • Amazing... By BeardedTridacna on 1/9/2017

    Installed easy, lots of great functions... After a week it began to send texts like "Resistance is Futile". I'm scared, and now it has taken over my household, it even turned the Keurig against me. Note: It made me give 5 stars. Please help me.
  • Affordable Par Meter By ML on 12/18/2016

    Worth the money just for the par meter! You may be surprised how high or low your lighting is until you get one, I sure was.
  • Inexpensive PAR meter By Bob on 12/11/2016

    It works but not with Apple unless you get the wifi version.
    I bought a cheap $99 notebook PC to use it.
    So for $260 I have a PAR meter, by far the cheapest option out there. Who knows maybe I'll set it up for temp redundancy in the future.
  • 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!!!!
