I'll following along.
I too have a 40 breeder, but a ATI 6x39. I hope I don't bleach my lps and sorties with the lights.
Sorry, haven't checked in on this thread in a week or so... I will say that my four bulb ati is quite bright at approx 12 inches above the tank. With 6 bulbs you can program them to only have 2 - 4 on at a time if you so choose.... lots of options with 6 bulbs



I did make a modification to the bubble trap so a fish could escape should it happen again. I did pick up a firefish the other day and he is getting along great with the gramma
