Help with colors

[newsalt]

I'm working to get to a ULNS. I have a 180g tank with a net volume between the tank, sump, piping and equipment of 200g. I'm currently dosing the following:

Phol's Xtra: 4ml/day
MB7: 10 drops/day
Coral Vitalizer: 8 drops/day
Biofuel: 8ml/day
Zeo Amino Acids: 3 drops/day
Sponge Power: 8 drops/day
Lugol's: 1 drop/day

I'm having trouble getting the blues and greens to really pop. I know iron will help the green but I'm afraid of overdosing and getting algae problems. I thought the Lugol's would help the blues, but it isn't. Any ideas what I could do?

reeflux 10K bulbs will get you blues and amazing growth but you wash out some of the other colors.

I've seen 20k bulbs that really made corals pop

I'm using T5 lights. I have a 14 bulb fixture from Aquactinics.
