Andrew's Red Sea Reefer 250

[Darkxerox]

I turned the intensity down from 65% to 50% after I made those measurements. A rough estimation now is 160 PPFD*(50/65) = 123 PPFD. I'm not actually sure there is a linear relationship between the intensity knob and PPFD. It would be a good experiment to do with the club's PAR meter...

What temperature are you running the tank? Seems like they got wiped out pretty badly in the last bleaching event so curious to see what you've been sitting at.
