Coral lighting

Hey, knowing that u guys are experienced reef guys, what are decent bulbs or K rating's to promote good coral growth?

yellow =lots o' growth, but bad color 10K
white = some growth, semi-good color 14 or 15K
blue = minimal growth, color that popos. 20K

Granted this all depends on the make/brand. Some lights are barely even blue at 20k, and some are start white at 10K.

What may work best though is MH supplimented with PCs or VHOs. You get the best of growth, but you can suppliment to adjust to the color you want.

I guess what I would ask you is what are you trying to accomplish with your lighting and what are you keeping under it?

actually i'm setting up a new tank, and i'm just figuring out what corals i can have depending on what lights I can get for a decent price

I'm personally aiming for *yes your guessed it, well maybe not* "acropora" frags and or SPS in general.

hmm oh yes and currently I'm leaning towards these http://www.thatpetplace.com/pet/prod...tm_term=209268
bulbs as they are fewer $'s then the other ones and they work for my tank top/light system

I was reading about a few 14k 50/50 bulbs, well more accurately tank packages, and the match I found closest to those bulbs were the ones above so thoughts?

Currently I have one 6.7k compact fluorescent bulb.

With those bulbs the best you could keep is probably softies, some zoas, some LPS, and MAYBE some forgiving SPS. The intensity isn't enough to keep the vibrant colors that most SPS have, it may also hinder their growth.

so, just maxing out all possibilities here, what would be a rated bulb/stats of a bulb for acropora corals? (other then metalh's)

For SPS, you can try either metal halide lighting, or overdriven T5s. T5s are popular in Europe and gaining popularity here.
