Looks like you have under control. Just make sure you keep a close eye on your corals for signs of stress. You'll be riding the ragged edge with that setup; the outcome will either be glorious or disastrous :wink:

Oh, I see you're getting the XM 14K bulb (isn't that 15K?), a notoriously low par bulb. Should be your safest choice for that setup.

Agree it will be great for acclimation but you might want to switch them with a higher par bulb later. What Ballast are you going to use?

J

the type of the ballast i will find out today, but what do you meen higher par?
does that meen higher kelvin, or better quality bulb?

"Photosynthetic Available Radiation" or something like that.

Here's the best halide info on the web:

ok i'll ask for that when i go buy a new bulb. i think the XM-15k should be fine

so with a 400-watt over my 33-gallon, can i pretty much keep all the acros, milliporas, and clams, that need high light?

Yup you should be able to. You may need to put LPS into shadier areas though.

You will probibly have some darker areas on either end of your tank with it being 3ft wide and using only 1 central light. Probibly not much, but it might be better areas for your LPS and softies.

all my softies are on the sides other than my xenia who is right in the middle, so i fear the worst for him, but i think he shud be ok, my cup coral loves light so he'll be ok and colt also worrys me even though he's on the bottom of the tank, all the way to the left
