just wanted to get everyone sharing their results. when i first set up my halide fixture(aqua medic 2x250 + 2x54) it had aqua medic 20k bulbs. it was putting out about 250par at the surface and 150 at the sand. a couple of weeks ago i switched out for curretn 10k bulbs. freddie40 came by the saturday after christmas to check out the tank and i tested the new bulbs. 1200+ at the surface and 400+ at the sand. i like those #s a whole lot more. anyone else want to share their results?
thx for bringing the par meter dave.
