Ok, so I am trying to get screw in CFL's for my 10G planted tank. I know that I want between 6500K and 10,000K color temp, however I am a bit confused about how to calculate my wattage.
I started looking at my hood, and it says 30 watt maximum, ok I get that. So I start looking at CFL's and they all say something to the effect of 26watts = 100watts, ok so as far as my hood is concerned 26watts, cool.
What about my wpg calculation, is it 100w or 26w? I'm leaning toward 100w for this calculation (I hope). I currently have 2 13w = 40w daylight 5000K CFL's, so is that 80w = 80/10 = 8wpg ?
Also, when someone says "you have low/medium/high light" do they mean the color temp, 10,000K = high light, or the wattage, 5wpg would be high? So is my 8wpg formula above low light because of the color temp, or high because of the wpg?
Thanks in advance for all the help.
