Whats the best color temperature for plants growth and fish visuals?

SunPaq Daylight 6700°K
SunPaq Dual Daylight 6700°K/10000°K

I think Dual Daylight will be the best because it has both 6700K and 10000K, which gives you the best plant growth and looks. Actinic is only for saltwater.

I would get the 6700k, current usas bulbs tend to be very blue IMO.

How many tubes does your tank require?

Another vote for Dual Daylight (6.7K and 10K). I think it's a very pleasing combination to the eye. However, I will add the caveat that I'm not sure it's the best for growth. Plant-specific bulbs usually appear more pinkish.

I currently use an 8 bulb t5 ho fixture. I run 4-6700k 3-10,000k and 1-20,000k and i really like the way it looks. The 20,000k was kind of a random decision, but since i added it the transparent fins on my angel fish have had a lot more visible color.

X2 if it's an option for you.
I wish they made these in 96 watt PCs

6700k/10000k looks great

If it's a 55W PC bulb, there is none better than the GE 9325K.
