I have a 20 gallon cube reef tank with softies, a few LPS, and a bubble tip anemone. When I first set up the tank and had no colorful coral, I set the light (AI prime 16hd) to a very white color. I modified the saxby preset to add in quite a bit of cool white. Now that I have kept the cheaper/drab corals without issue and have graduated onto more expensive florescent corals, and would like to switch back to a more blue hue so I can enjoy the colors more. Since white light isn't as photosynthetically important as the blues, can I just lower it all at once without issue, or do I need to adjust it slowly? I will not be changing the blues or other spectrums at all, just the cool white channel.
