Holy smokes ! Really??After pulling them all I still got over 300 par at 18" with them at 60% blue and 30% white. That's 5" in the water! I had to turn them down to get the 200-250 par at the top of my rock columns where my acroporas sit.
If you pull some and don't like it, nice thing is you can always put them back.
As you said Salty, these have power to spare! No joke.
I'm putting the new ones 9in above the water. I planned on pulling the half my favorite ones to pull again but.... I'm never going to be over 40% if that. Nice!!
