Giesemann Spectra - 400w Halide and T5 combo for SPS

[Scinature]

Hey guys,

I have a Giesemann Spectra 3x400w halide with 4x80w T5 (magnetic ballast). I am running an SPS dominant display, used for a grow out colony tank. Just switched from a 6x80w ATI T5.

What halide bulb and T5 combo would provide a natural look, whilst keeping growth and colour nice. I live in Australia, so brand name halides are difficult to come by.

Appreciate it, guys.

I really like Radium bulbs with 2 blue+ and 2 actinic
