Does it metter if the MH are a 10k or 20k? I have 2 250 14k in my 75. What would it look like under 20k? If you have pics of the same anemone under different k lighting pls post, if not thats ok.
Its a matter of astetics(sp). I prefer the 10k look, some prefer the 20k look.
Some say that 10K will make corals grow faster and 20k slower, not sure about that.
10k have a whiter look about them and 20k's a bluer look.
