20k t5 bulb combo

[Mrfresh]

well I switched back to t5s and I am trying to get that 20k look.
I have an 8 bulb light fixture that will be going on the tank.
which combo of bulbs should I get and which order if any should I put them in?

thank you

I've grown to love the ATI bulbs. I'd do a mix of Blue plus and Purple plus for a 20k look

I'm not sure what the K look of my tank but I'm running a Tek 8x54. Front to back
Blue +

I love the look. It is plenty blue and the coral+ bulbs have just enough of the purple in them that I was able to get rid of then in my set-up.
