PAR Monitoring Kit (ASM module and Real Reef Rock) – PMK

Features and Benefits:

Performs continuous light-level monitoring for your aquarium
Measures actual PAR – the light corals and plants use
Prevents burning out corals
Includes ASM – the new Advanced Sensors Module
PAR sensor hides nicely in aquarium inside Real Reef Rock
Fine tune your lighting to your aquariums’s needs

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.


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.

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!

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.


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 connect to your Apex and have their data logged.

ASM – Advanced Sensors Module
NPS – Neptune PAR Sensor

A Must-Have for Sensitive Skin
Size: 5 Fl Oz (Pack of 1)
recently tried La Roche-Posay sunscreen and I’m really impressed! 🌞 The texture is lightweight, non-greasy, and absorbs quickly without leaving a white cast, which is a big plus for daily wear. It feels gentle on my skin and doesn’t clog pores, making it perfect for sensitive or acne-prone skin. I also love that it provides strong, broad-spectrum protection while still feeling breathable. Overall, it’s become my go-to sunscreen—I actually enjoy applying it every morning because it feels more like skincare than sunscreen. Definitely worth it! I would be honored if you would consider me to receive a PR package. I’d love the opportunity to try more of your products and create authentic content that highlights the benefits of La Roche-Posay skincare. Thank you so much for your time and consideration! Warm regards, Andrea Mohanlall

It feels very good on the skin.
Size: 3 Fl Oz (Pack of 1)
I’ve been using this sunscreen for about a week now, and honestly, I’ve liked it even more than I expected. The skin on my face feels much softer and healthier, and one thing I’ve definitely noticed is that my dark circles are gradually looking a bit lighter and less tired. I love it because it doesn’t feel heavy, absorbs quickly, and doesn’t leave a greasy residue. I also like that it works well under makeup or just on its own for everyday use. For now, I’m giving it 4 stars because I haven’t been using it for very long yet and want to see more results, but so far, I definitely feel a difference in my skin. If I continue to see more positive changes, I’ll come back to update my review.

Blends nicely, is not greasy.

Light, blends nicely into skin. Does a good job of blocking the sun. I will buy it again before the summer is over.

Feels like nothing!
Size: 3 Fl Oz (Pack of 1)
Fantastic! I never write reviews but this is incredible. Just as advertised it dries quickly, doesn’t feel oily and doesn’t leave marks. And the coverage is no joke in this AZ sun! Held up during Memorial Day weekend at the pool all day. Excellent all around!
