## Description

Are your corals not as vibrant as you expect? Have you ever had an aquarium crash unexpectedly? Now with the seneye Reef you can continuously monitor and analyze key life-critical parameters in your saltwater aquarium to ensure that your corals and fish thrive. You can automatically receive alerts before conditions become toxic, giving you time to fix the problem without losing your fish. The integrated PAR, LUX, and Kelvin meter allows you to ensure that your lighting conditions are optimal, so your corals thrive and appear vivid. seneye Reef monitors: Temperature - 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 poisoning pH - 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 LUX - monitors ambient LUX and can be used to take direct LUX readings, understand how your light degrade over time Kelvin - understand where on the kelvin range your lights are and how light can change over time PAR - monitor the Photosynthetically Active Radiation (PAR), understand if you have the correct quantity and quality of light for your corals or plants One month seneye slide included - monthly slide replacements needed

Review: Best tool around for tuning your lights - What more is there to say? If you are running LED's with multiple settings for intensity and spectrum, or if you're rebuilding a LED array and are changing LED types, this is a perfect tool. The software is straight forward and the sensor is easy to use well enough. Just know the suction cup doesn't work all that great, but then again, what suction cup does? The Kelvin chart is a little misleading if you're running LEDs, but the readings you need for PAR and PUR are really useful. I know there are other systems out there, but this one gives you PAR and PUR, which is hard to get together in a nice package like this one. And the price is reasonable for what you get and what you can measure.
Review: Sadly, I cannot recommend this device. Readings Are Not Accurate. - I purchased this after a really positive video review from Bulk Reef Supply. Sadly, getting mine set up was not easy. I even went so far as to purchase a mini Windows 10 PC to have this set up under my reef tank. All that was configured and the pH readings have shown me with a 7.3-7.6 at best. I was worried so I have taken water samples to have the water tested several times over the past month, and each time the readings came back right at 8.3-8.3. Temperature is also reading off. Additionally, when I show people the readings for the ammonia, nobody knows what the readings are supposed to be telling us, when all the standard test kits that people use are a standard number, not two different readings for NH3 and NH4. Thinking that "Surely I must have done something wrong with my slide. That must be it." I went and ordered another three pack of slides. I made sure the soak the slide for 48 hours, then installed the new slide, even though my original slide was less than a week old. New slide gave the same readings. When I researched the issue online I got a lot of nothing...except one person talked about making sure to seat the slide while it was underwater to ensure there were no air bubbles skewing the readings. I took the slide out, while the device was under water, and reinserted the slide without bringing it above the surface. Same readings. Do yourself a favor and save the money until you have the funds for a more trusted metering system. I sure wish I had. That's about $350 I've wasted (Seneye Reef, Mini-PC, 3X Extra Slides)

## Questions & Answers

**Q: Does the par meter work with led lights?**
A: These will work with LED, but Apogee that makes several Par sensors recommends an LED specific par sensor. We carry all of them, but the LED specific ones are pretty expensive.

**Q: Can u monitor mutiple tanks?**
A: You would need a unit for each tank, they only have one sensor to collect the data.

**Q: Does this come with everything I need to read the par at the bottom of my tank?**
A: You will need a computer with a usb port to plug it in to, and an account (free) with Seneye.  You have to replace a little card every 28 days or so.  Other than that it measures PAR pretty well.  BRS says it works as well as the $700 models.  Other than that, yes it will measure PAR right out of the box.  You will have to hold the sensor at the bottom of your tank to get a reading there.

**Q: Can you get readings from this on your phone or something? Or do you have to get the wifi monitor thing separate?**
A: This one you can only get data with a USB connection to your computer. TO get data on your phone, you would need the Wifi module, or the Reef Pak, which is a reef Monitor, Wifi module and a dry box package deal.

### ⭐⭐⭐ Mixed Feelings
*by L***T on October 18, 2020*

While this device offers some critical information in my reef tank, I am not sure if I am really happy with the product. There are very few PAR meter options at this cost (to own) that you can trust. This is a great option for 95% of people needing to measure PAR parameters. The temperature has been accurate enough when measured against my 3 other temperature monitoring options. Where I become less satisfied is the ammonia and ph monitoring. With the monthly consumable cost (~$11-$12/month) for the required slide, I would expect a better rounded website and application experience. While free, it is basically a subscription to get the most from the product. The application is a joke that redirects you to the website for anything beyond the last reading taken by the device. The website dashboard is clunky and requires some getting used to.
