Coral Acclimation to new MH Light?

[jjaalmaraz]

Hello all, long time no talk to. I do read posts here all the time though. I just can't seem to bring myself to read the ones here in Austin. Go figure. Anywho,
I just switched from Power Compacts (Jebo 36" two PC lights = 190watts) to one Coralife Clamp-on MH 150watt for my 30 Gallon Long.
I have two questions:
1. How long will it take for my corals to acclimate to the new light.
2. I noticed that it is raining down light in the center of the tank and the corners are darker than usual. I have moved corals out of the corners and closer to the center to get more light. Is the one light enough, or do I need another one??

It may take up to 2-3 weeks to get them use to the light..start the light cycle slowly you don't want to freak the corals out!!!

try to raise the light a bit to get more light to the sides??? If it is to low it will put direct light to the center only!!

You shouldn't need to do anything special, maybe just lower your light duration to 75% of its original length.
