Lighting help LED too magenta

[jstuver]

I am currently running this fixture AJM Reef LED on my 30 gallon zero edge tank. The tank measures 30" long 18" front to back and 12" high. It was giving me dark corners and not enough spread so we removed the optics from the LED's which gives me better spread however I haven't been able to figure out how to make it look not so magenta! I don't know if the blues have a red tone to them or what but the corals are looking brown/purple to me. I light acclimated the corals from a 250 watt metal halide to this fixture and only lost color in one or two things that were up too high.
Anyway I am on the fence about just getting rid of the LED and going with a ATI T5 6 bulb when I can get the money saved up.
I guess another option would be to build a floating hood and retro fit some T5's into it along with this light.
Today I messed around with the settings a bit and turned the blues down and white up which I think may have helped a little but I don't know lol

Here is a full tank shot:

Turn cool blue up to maximum.

It doesn't let me run the blue colors separate as far as I know. Only whites which I think control the reds, greens as well and then all the blues are on another channel

Well, that stinks. And it's for that reason that in DIY I never recommend two colors be run on the same channel. :/

Basically, that purple light is made by mixing lower blue (450nm-ish) with higher red (630-80nm-ish). Cool/standard blue and cyan mitigate this look almost completely, but since you don't have cyan and don't have control of the cool blue, unfortunately I think you're stuck with it.
