Okay so I have 120 gallon sps dominated system run under two radion xr30w gen 2. I am not satisfied with the growth and coloration that I am getting under them so I am going to add add one t5 retrofit light on either side of the radions (so two total). What two bulbs should I use? I would like to get more coloration rather than growth, especially in the red and purple color range.

Personally I added 2xT5 to my it2040 leds (over a 38gl) and believe 2 more would be better.
I think you should consider hard adding 4xt5 minimum. Also factor in 2 additional just incase :)
2 blue plus, Aquaspecial and either purple+, or actinic

So I should add a total of 4 retrofit fixtures?

Blues 11:00 - 17:00, purples 10:00 - 18:00. Kessils ramp up slowly through the day to low moonlight during the evening and all out at 22:30.
