| Re: Lighting: Mixed of blue and white The light that I use is Aquaz T5 HO. The blue is Aquaz Blue Pro 420 to 470nm wavelength range. The white light is Aquaz T5 HO Ocean Pro of 20000k. Now the lighting mixing is 2 blue and 4 white, but it look like to white a bit yellowish and the color of the coral it not very attractive |
