I do have to ask,
What type of system are you setting up? Reef / mixed reef / FOWLR, etc... your sig shows a Fish Only tank which would be a completly diffrent setup then a reef of that size.
What are you going to use for sump and return pump?
Its hard to answer the question without knowing what you want to do with your beast.
BTW: How much did it set you back?
for a reef, you need flow, lights, refuge and skimmer
Flow:
a minimum of the TurbelleÃ"šÃ‚® stream Kit TS48
I would however look at getting the 6200's instead of the 6100's as the diffrence is around $400-500 and would be cheaper then having to sell and re-buy later on.
Lights:
Depends on your tank specs, but I would "think" 4+ 400w MH
Skimmer:
I agree, go with the AP1003
Refuge:
Look around, there are so many large refuge setups around here you could set something up fairly cheap.
