T5 438mm tube options?

[Katch]

I've just upgraded my Romo 90 to T5 lights and went out and bought a pair of Juwel tubes; Colour and Nature.

These are supposed to have a colour temp of 6800 and 4100 respectively. I though this mix would look quite natural but it has a very yellowy cast to it. Juwel also do a Day bulb at 9000 kelvin and a marine at 15000k that I might try.

Is anybody else using these short 24w T5 tube and can suggest a bulb combination that will look nice and clean?

Hi,Katch,
I have Day+ Nature and there is still a yellow.Nature have a lot of yellow.Only Day-such a nice green plants in the tank.
May be Day+Colour will be a better combination for your eyes.
