whats some good lighting

Okay, so, recently I had a mysterious death of my two fish while I was away, mom was caring for them. I went to my local fish store, they tested the water, yadda yadda, its fine. They had no clue.

But the corals are great! So I plan on getting them going amazingly and stuff before I get more fish. I've been adding zooplankton and stuff, "fuel" from aqua vitro, as well as "calcification" from them too.

I have mostly polyps and soft corals. Like anthelia and kenya tree.

But I want to get other stuff, and I want to expand to more tanks,
but whats the best lighting I can get, with the best deal (links would be appreciated) for a tank thats 40gallons(a breeder).

I figure I'll use this as my corals tank with a couple fish, and eventually spread out with a bigger(obviously) system, with more fish, more corals, the whole works.

 

lol you could do a 4 6 or 8 bulb t5 and keep anything you want, setting up a 40 breeder for my wife and im thinking 6 or 8 bulb, if your gona stick with softies then theres really no need for more Hp
