250 w is a bit over the top for a 20g. i would just use 150 or 175

250w is alot, you going with a 20L, 20H or 20XH? with that much light your gonna have to invest in a chiller and possible ATO. I would just do the 150w MH and the softies should be fine.

	MH Metal Halide Lighting, typically used for high intensity light demanding corals such as SPS. Bulbs come in varieties of spectrums (7k, 10k,20k), and intensity (175W, 250W, 400W).

250 is gonna burn most of your corals in that size tank I would stick with 150 or go with t5's

I agree to the above post, 250w is over kill for that size tank. Save your money and go with 150 or 175w.

Get a 14k 150W bulb and you'll be fine. You won't need any additional supplementation from the PC's.

If that is really what you want then get a bigger tank.
