Noopsyche on 210

Looking at switching from fowlr to softy and lps. How many k7 pros do I need for my 210 standard dimensions.

I have one I picked up on the classifieds here and hung it over a 40B frag tank. Its a lot of light for that tank.
But I imagine at a minimum 4 would cover you? Spread out over your 6 foot tank about every 14 inches would give you a decent spread. Especially for softy's I think that would be good. Obviously more is better but 4-6 depending on your budget.
