Continuous light-level monitoring for your aquarium
With the PAR Monitoring kit, you can monitor and log your aquarium’s light levels 24 hours a day! The perfect tool to fine-tune your lighting on your tank. Now you now can adjust your lights with the confidence of knowing you will not be giving too much or too little light to your corals and plants.
Prevent Burning Out Corals!
At certain parts of the spectrum, the human eye cannot perceive light intensity changes once the light level exceeds a certain point. Too often this causes people to adjust their LED lights far past the ideal PAR level for their corals or plants. This usually results in burning, bleaching and/or death. With the PMK you can adjust your lights while monitoring exactly what light is affecting your corals and plants throughout the day. Also, not all corals are alike. Each type of coral has its own range of light intensity that makes it happy or not.
Rugged Sensor Hides Inside Real Reef Rock
Sensors and probes are great in our aquariums, we just don’t want to see them! That’s why we usually put them down below in the sump. Not possible here. Knowing this we had the guys at Real Reef Rock design a custom piece of rock to hide the sensor in your aquarium. Now you can monitor light 24/7 and never see the sensor!
Measures Actual PAR – The Light Corals and Plants Use
The Apex with the PMK measures actual PAR. PAR stands for Photosynthetically Active Radiation. This is the light from 400 to 700 nanometers that organisms are able to use for photosynthesis – this includes the zooxanthellae algae that lives inside your corals. Other measurements like LUX are not useful at all as they measure just the light visible to the human eye.
24/7 Light Monitoring!
Track your light levels over time. With the PMK you track and log PAR 24/7. Now you easily go back and look at how you had your lights running last week. Even better you can compare your light output across the day with others who use the PMK and then compare light schedules and LED settings.
No more guesswork!
If you control your lighting with the Apex, you are in for an added bonus. The lighting wizard in Apex Fusion shows you your previous days light level across the day superimposed with the light wizard graph. Up until now, you had to pretty much wing it when it came to making adjustments. Now you can easily make lighting changes and see the effects of those changes in one simple interface! If you don’t have it already, this is one major reason to start controlling your lighting with the Apex. There are many Apex Ready light choices available. Some of the wireless lights like those from AquaIlluminations and EcoTech Marine even have their own Apex control modules (AWM and WXM).
Includes the newly released Advanced Sensors (ASM) Module!
More information will be released on this module in the future but in short, this new module allows for hundreds of different types of future Neptune Systems and current 3rd-party sensors to be connected to your Apex and have their data logged.

Well worth the money By Bakerrichard27 on 9/1/2017Bakerrichard27 would recommend this product to a friendIt helps with coral placement and helps monitor algae growth in my system I can normally tell when I have increased po4 or nitrate when the sensor reading decreases par from its day to day location I love it
LOVE IT!!!!! By Carlos on 8/8/2017Carlos would recommend this product to a friendIf you have an APEX and a REEF TANK this is a MUST HAVE!!!! it works great and I like how you can check the PAR constantly in the APEX FUSION!!!
Must have for SPS By Polymorphyc on 7/5/2017Polymorphyc would recommend this product to a friendNow this is not the 1st thing you need to run a successful reef, but as your reef evolves, it becomes a necessity. Personally, I was just having average growth, but after PARing the tank I found I was in the 250's, when I was shooting for the 350-450 range. It made a big difference for me, and its simply something that can not be determined by other means, Highly recommended.
works as expected By Casey on 1/3/2017Casey would recommend this product to a friendThis thing is great. Everything you think this does, it does. It's really nice to be able to put this next to your light curves and see that it's working as expected.
Helped identify a long going problem with my tank By DRock on 12/4/2016DRock would recommend this product to a friendWhen I first tried this product I thought it was defective. I am running Vertex illumina SR260 and a SR360 (two different tanks). With both fixtures I was only able to get PAR to around 160 at 12-15 inches below the surface of the water - this was with both running all three colors at 100%. The tank looked bright and light, but not getting anywhere near the PAR required for SPS which has been driving me crazy over the last four years. To test the equipment i took an extra Apex JR with my PAR meter to my LFS and took reading in their tank and was getting anywhere from 200- 600+ which is consistent with what they were getting with their PAR meter (confirmed my readings with the same Apex JR setup). After looking at this I ordered 4 Radion Pros to replace the two sub-par fixtures. Now i have two 36 inch expensive (about $4,000 spent on the two fixtures) LED fixtures that would be perfect for a fish only tank:(.
MUST MUST MUST have for SPS owners By BlennyKravitz on 10/19/2016BlennyKravitz would recommend this product to a friendBoy, is this thing humbling. I had my lights too far away from the surface and not turned up high enough. Chasing parameters and element dosing and the stupid AP700s were just too far away - lol. Like never revving past 3000RPM in a Porsche, but I have been putting race fuel in it and tuning it all this time…
So far, Apex has been the best $1500+ investment I have made on this blasted hobby! Funny thing is, I went to the LFS last week to buy a fish trap and I ended with this Apex and a bunch of expensive coral - but I got the fish trap for free!
Local LFS did not have PMK in stock and I am man of immediate gratification, so I came to BRS to see if they had a PMK available for next day air. I ended up finding SO MANY OTHER THINGS to buy that I missed the next day air cutoff. I replied to the confirmation email requesting to downgrade shipping to 2nd day air and not more than 5 minutes passed when I received a message that the they had confirmed the warehouse was still going to process my order and get it to me the following day.
I placed the order in Los Angeles at 3:40PM and I was reading PAR levels the next morning by 11AM.
three thumbs up to Neptune and BRS! I would give four, but the rock they gave me was too tight for the sensor. I foolishly jammed it in and it was extremely difficult and scary to remove, so make sure you can get it out if you want it out to attach to a PVC pipe to move around easily...
Love this product! By Mike on 10/14/2016Mike would recommend this product to a friendI thought i was slowly killing my corals with too much light but after receiving the neptune PMK i found out i only had a par of about 100 at mid tank so i adjusted my kessil AP700's intensity to get mid tank level par to around 200 and after about a month all my corals which are mainly sps and a couple clams are looking better than ever with new growth. If you have LED's and an apex controller the PMK is a must have!
Great stuff! By Mike on 10/14/2016Mike would recommend this product to a friendGood product a good price, you cant beat it. The mixing instructions were very easy to follow also.
Par monitoring kit By Kevin on 6/7/2016Kevin would recommend this product to a friendNeptune par kit is awesome it nice ti keep up with it in a sps tank
Great to tune lights By craig on 3/23/2016craig would recommend this product to a friendThose with reef tanks have probably spent a lot of time and money on selecting lights... this allows you to tune them for optimal coral health and map out tank to determine where corals will be happiest in the water column. If you have an APEX Controller, this is a nice upgrade. I found immediate benefit in the looks of the tank (I had lights on much too high)
Worth It!!! By XocyrusX on 2/8/2016XocyrusX would recommend this product to a friendI switched my tank around and suspended my light. No clue where to start if I didn't have this. Tested my old tank and matched my new one. Perfect! Moved corals over and will start ramping up till I see their sweet spot. Thanks BRS and Neptune!
No more guessing... By Matt K on 10/2/2015Matt K would recommend this product to a friendI had been loosing new corals rather quickly due to STN. I thought for certain I was 'shocking' them with my LED lighting. I was wrong about that!
It's expensive. So are corals. Now that I know the corals are receiving enough light, I can look at other factors should I have any issues.

While the Neptune can control on/off functions for lights, and can connect to many LED fixtures for dimming control, ATI has now integrated the control into their fixures and they don't have a way to connect the 0-10v control to the Apex. If you wish to monitor PAR through the Apex, you will still need the PMK/ASM module setup as this function is not integrated into the base unit.
We have used the PAR meter for Neptune systems in our T5 and Metal halide tanks with great success and it works as well as any PAR meter currently available. For LED PAR readings will be slightly off depending on what color LED is turned on and will not give 100% accurate readings for growth. You will want to consider the Seneye as an alternative option which has better reading of LED light. Feel free to let us know if you have any further questions!
Great question! You will need an Apex Controller in order to use the PAR Monitoring Kit.
