I have been trying to find some info regarding the PAR numbers suitable for several kind of corals.
I found this article: Classification and Terminology For Reef Aquarium Lighting
Looking at the Blundell's Lighting Scale they came up with some kind of classification/scale (1-10) for corals:
Low Light 0-4 0-400
Medium Light 5-6 500-600
High Light 7-8 700-800
Very High Light 9-10 900-1000
Those PAR numbers seems very high to me. For example a SPS coral with high light requirement would need PAR between 700-800.
What is your opinion on this?
For those who have measured the PAR numbers in your tank what numbers did you had on average?
Thanks for any input
