So I am finding a good number of my SPS are turning the same color- it is green and purple. quite a nice color but I don't want them all to look the same. My lights are aquaticlife HID: 2x 150w (10,000K) MH, Giesmann- 1 pure actinic and 1 midday (6000K). all water parameters are good. The lights were a bit old ans I changed them today- same type but changed MH to 1x 14,ooo and 1x 20,000.
I presume the coloring is due to wavelength. do you think it is just due to the old bulbs ( about 8 months) or due to the bulb selection? thanks
