Acan + light advice for 40 breeder.

[daninfamous]

Im about to buy the lights for my tank im setting up a 40 breeder 36 x 18 x 16

I want to get a 4x39 t5 fixture either tek or aquaticlife (lfs has me sold on it and a great price)

Ive never kept corals I just have a FOWLR nano but I want corals in my 40b for sure, and I like the look of acans a lot.

Will the 4x39 fixture on legs (approx 2-3inches above the tank) be too much? can I get some advice, and bulb advice. Id rather not hang the fixture but If i have to I guess i will
