lighting question

[j30167]

I have a 8 bulb t5 fixture it came with 4 10.000k and 4 actinic 460nm bulbs, should I change any of these if so what would you recomend it is on a 90 gal

it's trial and error.. but all comes down to personal taste in how you want the aquarium to look. You can prefer the super bright... which is XXX 10-12k bulbs and an actinic... or you can add a pink bulb... to make the lighting more subtle. and with actinic.. run a 450nm and a 420nm bulb which makes things look a little more purple...
