Reef tank light recommendations

I plan on a reef tank build; I want to keep zoas, soft corals, mushrooms, and possibly SPS.
What lights would I need ?

This is the tank: 20x20x8 3/8" Acrylic AIO frag tank with black bottom | eBay

I found this Aquarium Lighting T5 Fluorescent Light Fixture: AquaticLife T5 HO Dual Lamp Light Fixtures

would 2 of them be okay?

Thanks!

 

2 of those fixtures will be more than enough. You will need to suspend them about 12 to 18" above the tank to keep from light inhibiting the coral. Nice looking tank BTW.

 

How would I go about suspending the fixtures?

Thanks!;D

 

Most lights come with a kit and there are after market kits you can buy. Or a DIY project with cable from lowes and "S" hooks.

 

Thanks a ton!
