Back in the day we never measured lighting PAR. We looked at how the coral was doing and either moved it up or down in the tank. I Got a suggestion from a member that we should ask about PAR and measuring PAR so let's talk about it today and how much you consider it!
From World Wide Corals: What is PAR? Photosynthetically active radiation, otherwise known as PAR, is roughly the number of light particles penetrating the surface of the water and saturating your tank. These particles supply photosynthetic organisms such as corals and plants with the energy they need to break down sugars, produce food, and cycle toxins out of their bodies. As such, they’re key to maintaining the health of your tank inhabitants and keeping the ecosystem in check. However, you must regulate the amount of PAR you allow in your tank to ensure your specimens are neither over- nor undersaturated with light. This is why reef tank owners often use PAR meters during the building process to find the proper light range for their specific aquariums. Read More Here
1. How much do you really care about the PAR values in your reef aquarium?
2. If you do care then how are you measuring your par values?
