First build - needing advice

[gridley]

My wife and I have decided to make the switch to a salt water aquarium after more than 20 years of freshwater. We purchased a used 110 gal tank with stand, sump and canopy. I am just completing the refinishing of the stand. I am reading about placing rigid styrofom insulation under the tank. What are the benefits of that?

A second question. The canopy we have has three T5 bulbs in it. Is that enough for a reef aquarium?

Thanks
