2x6000 or 2x6100??

[Infinitereef]

I have an 180g AGA tank. 6ft long. There are people who recommend me 2x61000 and yet another group is saying 2x6000 is better. Which one should I go.
My tank is Bare bottom and probably will got towards SPS in the future.

if you have bare botom and you are going to go sps i would go with at least the 6100 but would recomend the 6200. i have 2 6100 and 1 6200 in my 175 gallon and am hopefully gonna get one more 6200

I think 2 6100 is the best choice.
