I have a 100gal that im going to be setting up in the next couple week. I am going to be going with a 4ft light setup that I won at the last meeting(THANKS MAAST!!! ). I will be having two 400W MH's and two VHO's. This is way more lighting that you will have with that JBJ, but should be perfect for that tank. You might consider something similar. BTW, the tank will be open top with a floating pendant/canopy about 8-10" above, that im going to build.
