Is a 400W XM 10k SE too intense for a 21" deep SPS tank?

Tank is 36"L x 18"W x 21"H - 58g Oceanic - No Center Brace

anyone use a single 400W XM 10K on their set-up? if so, what size?

Yep... well, not a single bulb, but I'm using 400W 10K XMs. I've got 2x400W SE XM 10Ks on my 90g, combined with 2x54W HO T5 actinics and LOVE the colour -- it's like crisp, bright sunlight. Sorry I can't post a pic now (the lights are out as it's the middle of the night), but I can try to get one up tomorrow. It may not help too much anyway as my camera doesn't usually do justice to actual colours; it's an old 'point and shoot' model that does everything automatically and it tends to show things less blue than they actually appear.

In answer to your first question, I don't think a 400W 10K is going to be too intense for a 21" deep tank (my tank is 24" deep), but it will be quite bright. SPS will love it, and as long as you acclimate anything less demanding like softies or LPS they'll probably be just fine -- my tank is primarily softies so far (lots of zoas, palys, yellow polyps, leathers, Florida rics, yumas, shrooms, GSP and one little acan) and everything seems happy as can be basking in the sun :D

i have a 250 se 14,000k hamilton over my 18" deep cube. it works fine for my sps. i would think a 250 10000k would be plenty for you.

I had them, My sps loves them, My zoa's not so much. Well blues all mine turned brown. The sps loved them though.
I like the color.

I use 400w 20k on a tank that is less than 11 inches tall-all softies and they love it. good luck
