what t5 bulb combo in a 4 bulb fixtur?

i have a tec 4 bulb hood and need to replace my bulbs and was wandering what people would recommend. this is on a 75 gal. i do like the 15k to 20k look.

For most of my daily light cycle I use 2 uvl actinic and 2 uvl actinic whites. The intensity is not epic but I am getting good color and growth, but I also have a fifth lamp that comes on for 2 hours/day. HTH.

Maybe 1 actinic white and 1 ATI aquablue special for daylights would give you a better balance.
