For a while I thought you were asking about lightning

If I were you, I would have the actinic light come on a couple of hours before the main light and have it turned off a couple of hours after the main light. This lighting regiment would be more natural to the animals. Can you imagine someone switching on all the lights in your room after a few hours of darkness?

It'd also be better if you leave all the lights off for at least a few hours because fishes are not unlike us humans; they need their rest as well and when blue actinics may seem dim to us, they are actually quite bright to the little critters in your aquarium. Actinics are actually for us humans to admire the luminescense emitted by some of our corals, they serve no purpose to the welfare of the animals you keep.

Michael,

u mean the actinic blue got nothing to do with the health of the fish/corals or anything?

Definitely not for your fishes but there are some people who claims that the light spectrum emitted by 03 actinic lights are good for certain corals; but I'm not so sure about that. I use acticnics because I like the look of my tank when they're turned on.

Hmmm... dat's wat i was told too... dat's why i asked....

Apparantly some people said that the actinic would help some corals...

Anyone can provide more insight?

yup I have been told be4 that actinic is need for the growth of some coral, but no matter how I search or read, I never come across any point that mention the importance of the use of actinic. Just that got alot of point out to use actinic but no info on why must use it..

ok.. some idiotic question?

wat's the different between fl light system and actinic light system?

is it just the tube diff? can i just take out the fl tube and put in actinic tube?
