Hi can I use a b series 120cm on a 121.92cm x 35.56 x 35.56 aquarium?substrate height is 6.604cm. Would I still get good plant growth and bring out the reds in my plants?
Yes B 120 is okay. But please not the B series light cannot adjust each color separately, only total brightness.
If you wanna better color rendering, recommend WRGB II Slim 120 light.
