Honestly I think the heavy blues are for us and how we perceive the coral’s colors with them.
What are the radium’s color? 20k?Fwiw here is old school halide lighting on a mixed 210. Radium 250w x3 and 2 diy led bars consisting of 18 hyper violets and 18 royal blue 3w diodes. Very neutral white with a hint of blue in person with decent coral color pop. No photo editing or filters Gives the fish and corals a natural look but still some color pop
Do we really know that? I´m not so sure on that - what I´m sure of is that it often see this claim here on R2R - but have not seen any investigations that really show it.Today we know differently but what exactly is the BEST percentage combo to experience the best coral growth from a lighting aspect?
Corals really don't use much of the yellow and green in the middle of the spectrum.
Not as simple as Blue vs. White. White light is made up of all the color spectrums that include the blue spectrum. Generally speaking, the most beneficial light for corals and their zooxanthella is light in the violet to blue green portion of the spectrum (that includes blue) and a little in the red orange to red spectrum. These colors are at each end of the visible light spectrum. Corals really don't use much of the yellow and green in the middle of the spectrum. Unfortunately, there is normally a lot of those in standard white lighting. It may be that the benefit of using white light is just to replace the red spectrum that is missing from blue lights.
Take a minute and figure out what this chart really says according the penetration of different wavelength. the black circle will make the windex look. You can´t role out red just because pf penetration - when you need to tole out the windex wavelengths too. An in nature - its a lot of corals 10 m and up
