What Type of lighting should I use

[joker3762]

I have a 100 gallon tank with 2 starfish (1 Choc. Chip and 1 Sand Sifter) 4 clowns,1 flame angel, 1 blue tang. I also have 9 snails and about 8 crabs. I recently had 1 coralife 10000k bulb and 1 coralife 16000k bulb. I needed to change my lights as they were getting old. I could only find Hagen lights now. So I purchased 1 18000k light (Power-Flo) and 1 Actinic (Marine-Flo) Is this correct? Should I change the lighting back? :help: I just put the Starfish and Tang in 3 days ago. I know the old lighting was good for the clowns and Flame Angel
Thanks

The tank is gonna look VERY blue, imo go with a Actinic and a 10,000 K (daylight) bulb

Yes it does look blue, If I get rid of the 18k bulb and put a 10k bulb in what would happen? also I am reading that these should be on at different times? I only have 1 timer and its all in one fixture. What are your thoughts?

a 10k with an actinic would give it a cool look. Like a crispness with a hint of blue

Ya, get rid of the 18,000k and replace with the 10,000k. What most people do is run the actinic for an hour or 2 before the 10K comes on, keep the actinic on while the 10K in on, and run the actinic 1-2 hours AFTER the 10K light turns off to give a dawn/dusk effect. It isnt necassary, but its more like what the fish would experiance in the wild
