Ok for Kimi and Slowjazz, 10k is the Kelvin measurement of the light. Simply put, the spectrum. The higher the "K" (kelvin) the blue-er the light. 10k is a good all around day light color. Nice and white... That is why you run the "dim" (probably actinics) and the brights at the same time. That way you get a little more blue spectrum. Lighting depends on a lot of things. If you are just stocking your tank, you are going to want your coral and such to acclimate to the light, as well as the water. So do your acclimation with lights off. Put the coral lower in the tank, and gradually raise it up to where you want it to stay. I would suggest 1-2 hours of actinics (to give a sunrise effect) about 8 hours of full on lighting, and then 2-3 hours of actinics (sun down). This is what I do, and have had no problems yet. If you are finding that with that much lighting nuisance algae is cropping up, dial back the "10k's" a few hours and then slowly raise it back up to full time. Some people do more, some do less, it all depends on your setup, stock, and lights. You have to tinker with it, what works for someone, may not work for you. That is the best part of this hobby!
