My tanks are certainly not green like that, more of a "warmer" tone of white perhaps.
I do see something I mentioned before though, the former tube was one of those high in the red/blue wavelengths, creating a purplish hue. After that, any full spectrum will appear more green/yellow. But having said that, again, I do not see this extent in my tanks.
This is where dual tubes over the tank can help. If you have two tubes, have one this tube and the second a bluer tube. For several years I had one 6700K or 6500K tube with one 10,000K or 11,000K tube. It created quite a sharp white on the cool side. As long as the two tubes run full length, this works, as the light of each is diffused evenly.
