Lights for a 57 gal

[xobklynqt143]

im planning a little ahead, im going to be getting a deep blue 57 right now i have a 72 watt LED is that enough light? If not would 1- 120 work? i would LOVE to keep sps and some hard corals

I have had the same tank for 1 yr now and currently light it with a ACAN 103AC-24B which is roughly 10" of the water and grows everything very well. The coverage is a bit lacking against the far sides, but that is ok bc it is where I place my lower light corals. A 36" unit would definately be a better option for myself, but I am very happy with the results in the last year and the benefits are great such as no heat transfer to the tank, lower kw usage, and its 100% programable and zero maintenance. This light that I am running is 100w, and at no time does it ever reach 100% output as it is far too powerful. Hope this helps a little bit
