i received my par meter a few weeks ago but i havnt done much except play with it here and their, on boxing day i bought new bulbs so i did a quick before and after so i could see the differences, the old bulbs are about 10 months old
the one at the top is at water level and the anemone is about 12-13" down and the bottom is 28"
the light is on the tek legs all the way down which is about 6" off the water
the light is a 48"tek with 8 bulbs 1xatinic 1x22k 2x10k 1xcoral light 3xfiji purple
ive had great growth with this light and have been very happy with it,
