Here the run down. 29G tank, light by a 24" Finnex Planted+, hidden within the Aqueon deluxe hood. Ehiem spray bar(2x) and intake tube, connected to a Fluvial 206. As for plants and fish what you see is what I've got. Chili Rasboras up top, Green Fire Tetras below, Cory cats on the bottom and some Otos and a Dwarf Puffer, on snail patrol.
Here's the question, to quote my old friend Bill Shake-Sphere: Too Blue or not too blue?
With all LEDs (including blues) on.
LEDs (no blues)
I've been looking at my tank, with and without the blue lights on. (I cropped the images, but did not adjust the color.) The color is what my iPhone captures. I see the color the difference more on my iPhone then my iMac. Maybe your screens show it better. When I look at the tank in person the color difference is stark to me. The colors might also be lost in the JPEG compression. I'm hoping you can see it better on your computers and I do mine. The tank without the blue LEDs looks more yellow and has a deeper contrast.
I've come to like the tank without the blue lights on. It seems more green to me. What do you think? Is running without the blues on reducing the growth rate of my plants?
Only blue LEDs on
(I put this here for contrast) I never run only blue lights as I think it looks silly.
