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

Love them
Size: 5.5, Color: Red Pepper
I have gotten so many compliments on these shoes! They’re true to size and comfortable. Because of the material feet might sweat easier if hot but they dry quick. Quality is great and the color looks good, it’s more of a orange/red color. I got a 5.5 size
