-lighting question

[Der_Iron_Chef]

I personally think the watts per gallon thing is a bit unreliable. But from those who adhere to these standards, I would say...yes. I have 4 watts per gallon on my tank and have successfully kept all manner of LPS.

-alright reefkeeping does tend to be trial and error, but hey i'll give it a shot.

[honkey sauce]

if you had a 400gal tank with one 400w light in the middle with your corals directly under it that would be sufficient,thats only 1w per gal

[bv_reefer]

-o wow didn't think it's that sufficient, but definitely no sps right?

[Renegade]

it depends on how far from the surface the SPS pieces are. Also how far off the water is your MH

[bv_reefer]

2-70 watt double ended 6'' over a 33-gallon(cycling, but will be softie reef)
and if the sps frags were 5-6 inches below the surface, so do u think i can
try some sps?

[skylord]

The bulbs you're using could make a difference. But other than that, most sps like high flow and your MJ900 isnt going to do the job. Water quality is another big issue.
