VHO's too purple

I have a 125gal with 3 XM 250W MH supplemented with 2 160W URI Super Actinic 03's......the actinics come on about 2 hours before the halides, stay on when the halides are on, and then stay on a couple of hours after the halides go off.......everything looks fine with both the VHO's and MH's on, but I don't like the looks of the VHO's only.....they have a very purple look to them where I was looking for more blue or bluish-white......what could I do to get some of the purple out?
Thanks!

420nm is definately in the purple range and that's the peak of the URI SuperActinic. You can change the overall color by swapping one of the Actinics with an ActinicWhite.

Thanks for the quick replies.....is an ActinicWhite the same thing as what URI calls their AquaSun 10K?
A 50/50 is a combination of what frequencies?

So I would order the URI 50/50, not the AquaSun? Just trying to get the terminology correct....
If I do that, in your opinion what would be the best combo, front-actinic/back-50/50 or the other way around? My LR is stacked along the back wall leaving a large area in front for open swimming....
Thanks again guys...

URI used to call the bulb ActinicWhite. Sounds like they've renamed it the 50/50.
I like the Actinic up front. But you could try it both ways and see what you like best.

Bang Guy,
After looking around a little more, what URI calls the Actinic White is 50% actinic 03 blue phosphors & 50% white spectrum(triband).
Here is a picture with just the actinics:
