Mastering Reef Tank Lighting
When choosing your reef tank lighting , consider the color temperature that will best accommodate your coral collection. For a more vibrant display, you can opt for a combination of high and low- color temperatures to create a natural day-night cycle.
Most reef keepers prefer a color temperature between 14,000K and 20,000K for the ideal balance of coral health and aesthetics. Photoperiod: How Long Should Lights Be On? A consistent photoperiod mimics natural conditions and helps establish a healthy circadian rhythm for your tank inhabitants.

And quite frankly speaking, lighting is a complex topic. However, one aspect of reef aquarium lighting that often gets overlooked is the impact that lighting has on the aesthetic appearance of your tank .

Marine aquariums: Light spectrum is key - especially the blue range (8000-10000K and higher). Coral and reef organisms need specific lighting , often at 1-2 watts/liter, with advanced control systems. Color temperature - what do Kelvin ratings mean and how it can help with growing aquarium plants?
I have 2 redsea g2 60 LED lights. I didn't really care about spectrum/ color temp as I was fish only coming out of my cycle. I'm starting to add corals zoa, euphila, and now my first acropora stags. Some research on brs says run a ab+ spectrum so I set a color temp of 18.5 K for most of the day...
