Neptune PMK - PAR Monitoring Kit

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.

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.

At certain parts of the specturm, 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.The chart on the right shows this phenomenon without getting all technical.

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 atReal Reef Rockdesign a custom piece of rock to hide the sensor in your aquarium. Now you can monitor light 24/7 and never see the sensor!

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.
