20k Reeflux Question

[denverjon]

I'm currently running 250w 20k radiums on a Blue Wave 7 on my 120. I'm upgrading to a 210 and will be running 400w 20k reeflux on a coralvue ballast.

I'm just curious...how will the new 20k reeflux's compare in terms of color to the 20k radiums? And if I decide to go back to radiums, will they work ok on the coralvue ballast?

I run a coralvue ballest and I am running 400w SE Reeflux 20k bulbs.There color temp is around 15k,not 20k at all,Im honestly thinking of switching to a bluer bulb to get better chalice growth.

Thanks for the input. Do you think 20k radiums would work with the coralvue ballast?
