How about 2x250 watt ??
3x400 seems like a lot to me, You will have a fair amount of heat to deal with.

2x250w should be fine. I just mounted my diy pendant over my 45. It's a 2 foot tall tank and it seems like plenty of light.

i have my 110g with 2x250w halide. though it is suppose to be a zoo only tank...sps and a clam has mysteriously drifted in there. :D

they are doing great with great color and growth.

there always seems to be an ongoing thought for more light, more light and more light...but there is a point of 'too much'.

my personal preference are pendants with an open top for better heat dispersement...but that is just a preference...

yea i think at that depth unnecssary heat issues will be the result if you go with the 400's. the 250's will be plenty
