PAR is actually reported as: 200-250 molm2sec (micromole per square meter per second) or 750-800 molm2sec, not W (watts).PAR is actually reported as: 200-250 molm2sec (micromole per square meter per second) or 750-800 molm2sec, not W (watts).
The corals will only suffer when we don't adapt them correctly. If we do it slow they won't manifest anything wrong. You can see them adapting in terms of changing colors a bit in the process and sometimes they even stop growing in the beginning, but when they start to process and balance everything, including their zooxanthellae population, in the right rates, they get on track for their best growth and pigment production. I do not change them to a "better spot", never did. They don't need that at all. What we should do is to choose the best spot and leave them there, adapting the light slowly. Even the so called "deep water Acros" can support and do really well under halides at the top. So adaptation is the key. Trust me... any light change needs to happen slow and don't change it anymore. Only when changing bulbs. Try to get the same bulb always and adapt them to the new bulb. Changing spectrum or even ballasts could provoke new adaptation cycles. Not a big deal.
Brain fart - thank you for the correction.
Gotta stop drinking Jameson while perusing R2R
