In my 100 G tank I have a canopy on top, when I decided to start adding plants to the tank I upgraded the lights. I went from 2 regular fluorescent 48" bulbs to a retrofit kit with 2 48" T5 HO bulbs. ( both bulbs are White 6,500K and 54 watts ). So roughly I had 1.04 watts per gallon, but the canopy added 10" of distance from the top of the glass to the bulbs. I have been able to grow plants in my tank, like amazon swords, ferns, anubias, and wisteria mainly.
But I liked to increase my lighting to be able to try different plants (more lighting needs).
Last week I was able to buy another retrofit kit. I installed it also, this is similar 2 48" T5 HO bulbs, but this came with two different bulbs:
1 is Marine White 10,000K 54 watts, the second is Purple-Blue 6,500K 54 watts. So, after the installation now I have 2.08 watts per gallon, but now I have questions regarding the combination of bulbs and spectrums:
Remember I'm going to try medium to high light plants
1. Which spectrum is better for plants, the White 6,700K or the Marine White 10,000K?
2. Do I need to replace the purple-blue bulb with another white? To make it all 4 white bulbs?
3. What do you suggest for a bulbs mix?
Note: I don't have CO2 in the tank, I used root tabs, liquid ferts and excel...
