Why dont you wait for the 250's (or the 400's)? Ivan says that they're coming very soon.

I would hold out for the 250 watt DE's and see how much more they will be.

Do you really think I need this much juice? I still consider my self a noob as far as marine is conscerned. I was under the impression that 150 watt DE were somewhat equivalent to a 250 watt SE. Am I way off base here?

I think 150 DE are closer to 175 SE. 250 watts either way will be more light. If you want to keep SPS and get there colours to come out nicly i would wait for 250s

The 150's are nice lamps but you don't get a lot of spread out of them. For a 20" tall tank they might still be OK. I have a 150W over a 20g tank, 20000K lamp. Nice lamp, nice colour, but really (at least at that colour temp) not quite a lot of light. A 10000K or a 14000K lamp might be a neat choice though.

Robb, it depends what you want to keep. Here is a very nice tank lit by 2 - 150W 10,000K DE bulbs - forget what kind, I think AB. It is eposer's tank from a couple years ago. Beautiful tank, ask anyone who saw it.

I think he had a Spacelight about 8" off the water. Looks like a pretty successful tank, he even had clams on the sandbed at a depth similar to your new tank.
