Over my 90 is a 6 bulb. I thought about getting the 8 bulb but like your tank with the eurobracing around the tank the outside 2 bulbs would be somewhat wasted and would really just spill more light over the edge on the front and light the back wall of the tank.
The 8 bulbs are more designed for tanks like the 120 gallon with the 24" depth front to back.
