Lighting?

[Joeyv78]

I have a aqualight t5 ho dual lamp what would be the best combo for growing plants? These are the lamps I have





Ultra sun 6700k super daylight




Flora sun 5000k Max plant growth




Coralife 10000k not as bright as the 6700k



I had the 6700k ultrasun and the 5000k flora sun


Just swapped the flora sun for colormax and my tank seems a little dimmer should I put the floramax back in or what combo would be best?

I recommend any really, just not the 10k. I like 6500 range, plants love it too.

If you're trying to maximize your lighting, I would skip either actinics or colormax. Neither of those are optimal for plant growth. Beyond that, you can pretty much pick your bulbs based on your taste. The PAR differences between different colors of the same brand of fixture is usually pretty minimal (<10%), so you're better off getting a color that you like the look at. All 6.7k K or 10k + 6.5k are popular combinations.
