How many for a 120G mixed reef?

[Rybren]

I'm currently running two 7-year-old black boxes over my 4x2x2 120G. One of the lights is giving me problems and so it's time to replace them.

My tank is predominantly softie and LPS with a few Montipora thrown in for good measure. Would I be able to get away with 2 K7 Pros? The Tank has a centre brace, so three is probably not a good option.

Thanks

You will need 4 K7 Pro2
