Thanks for replying, the marine whites are marketed as 14k but look like pinkish to me.
This wagon the websiteof Arcadia for marine whites
I'll be getting some Marine blues
The mixed white and blue is not available but the LFS here has some china aqua blue knock offs. I'm just not sure if it's any good. My fixture originally contained ATI bulbs but it's no longer available here

Do you think these bulbs would work? Or should I go Change to MH entirely?

Corals like a lot of light in the range from 420nm to about 470nm which is in the BLUE range and a little light in the yellow and red range. Execessive light in the red range can actualy cause more problems than actualy no light in that range.
The 420 nm atinic Blues are going back to old school where it was thaught that those were the only blue frequencies corals utalized. However modern research found corals use virtualy many different band widths of light in the blue range. Also limiting the blue light to just the 420 nm range is not the most pleasing to the eye as it on the outer edge of the eyes sensetivity range and will always look much dimmer to the naked eye that it actualy is.
