That is one of the pros of using T5. you can have a diverse spectrum.
As compared to my 20k MH, both the temperature colours are about the same.
But the LED tends to give a little more florescence as compared to the MH.
Do note that for the corals, give them 3 - 4 weeks to get use to the change in light.
During this period, some of them might fade in colour.
some of my corals took alost 5 -6 weeks to colour up the last time after I swop from LED to MH
So I guess it is the same vice versa.
I can suggest that you purchase a couple of spare blue LEDs, and replace the white LEDs (maybe 2 - 3 on each set) to give your tank a more florescence look.
