Hello UKAPS friends,
Congratulation you have one of the best planted forums I've seen so far! This is my first topic here and I'm sure I have a lot to learn with you. Sorry for my english, it´s not my native language (I'm from Brazil).
I'm starting a new planted tank project. Its a 120 l tank, heavily planted, CO2 injection and 4x24W T5 Lighting (2xOsram Skywhite + 2xOsram HO 840).
I've got a question related to the ideal ratio between Lumens and Liters for planted tanks... I've seen some people say that 70 to 90 lm/l would be the ideal range for getting the best plants growth rate and good health. Is it true? What do you think about it?
Another issue that I'd like to understand is about the color temperature (K) of the light we use on planted tanks.. I've read that aquatic plants absorbs light above 6500K.. Is that so? What happens when you combine different color temperatures? Lets say 1 light bulb of 8000K combined with another of 4000K... Is it the same thing of having 2 x 6000K (8000 + 4000 /2)?
I know its a newbie question... but I'd really appreciate if you help me understanding these issues.
Best regards,
Gabriel
