Does anyone know how to calculate or even guess par readings based on ai hydra 26 settings? I have 2 hydras on a 40b 16” deep reef and plan on using the ab+ spectrum. I don’t have any access to a par meter but I feel like there should be some sort of calculation out there for something like height + light settings = ___ par.
Here is a picture of the ab+ preset but I plan to only run it 60-80% for a few lower light sps and mostly softies and lps any input on this would be helpful!
