I used to think that acclimation to higher light intensity and PAR for SPS, LPS, softies is successful if the rate of change is slow. I have some torches that I can’t get past 150 PAR without less polyp extension. I’m wondering if it’s not as simple as cranking up the lights slowly (I was increasing by 1% a day, maybe that is too fast?). Is there something else that needs to be managed hand in hand with increasing light intensity such as higher nutrients, higher alk, temp? Side note, but I’m dialing up light intensity to bring out coloration of my torches.
