acclimating sps to new stronger light?

[htownguy]

Hi guys. I decided to upgrade my lighting from a small pendent 250w hqi light to a 400w radium with the cozumel sun reflector. reason is I don't get enough coverage with the smaller reflector for my cube tank. 30x30x24. my question is how would you acclimate your corals to the new light? Right now I'm running the 250w about 12" off the water for 9 hours a day and 2 24" t5 Blue+ bulbs for 11 hours a day.

Hi!
Use time to acclimate and add hours gradually.

Just on an edge of caution you will want to acclimate your corals. I have changed from 250 to 400 MH's when I used them in the same fixture with no acclimation with no issues. The problem you are going to have is the new reflector. It will put allot more light in the aquarium which can bleach everything.

Yea that's what I'm concerned about. I guess i can just hang the light higher and i'll start off at 5hrs a day and see how that goes.
