ok will wait for your pm. What is the concern with the low par really? They can survive at slightly lower par but dont keep them at like 50 or something, not optimal for the health of nems. Nems are smart in a way in the sense that they can move if they get too much light unlike other corals.Oh, very interested in the 2" er. I will send PM shortly. My major concern is you are throwing A LOT of par at your widows.
