T-5 Giesemann bulb combos

[Blue Ring Octopus]

I have two T-5 lights both Giesmann
One is a Matrix 4 bulb dimmable only
The other is a Giesmann 150 MH with 4 T-5 bulbs
Which bulbs should I get?

For the 4 bulb, something along the lines of 3 blue plus and 1 coral plus.
With the halide, I'd run two actinic and two blue plus.
I know I am referencing ATI bulbs, but Geissmann sell comparable spectrum bulbs if you want their brand.
