Currently running two of each of these URI VHO tubes on our 3' 67g. Don't like the colour of the corals under them as everything looks sort of brown, even with the two actinics

Tubes were changed about 6 weeks ago and there was no improvement in colour:
URI VHO Aquasun, 10000K:

URI VHO Actinic:

Am thinking of dropping the Aquasuns and using Actinic Whites instead. Does anyone have experience with these tubes? Will I notice a colour difference in the corals?
URI VHO Actinic White 14000K:

Are there other VHO tubes out there that will perk up the colours of my corals? Will continue to use the URI VHO actinics.
TIA
