Just got my par meter in and here are some readings from my tank 48" dual aquaticlife fixture with a midday sun bulb and a coralife 10k and a 48 " finnex ray 2 ds. At 6 inches the aquaticlife showed 90 par and the finnex read 115 and with both it read 200 par. At 12 inches the finnex showed 70 and the aquaticlife fixture showed 50 with both I got 130. At 19 inches(the bottom of my 75 gallon) the finnex read 50 par and the aquaticlife read 40 par. With both on it read 90 par. The fixtures were staggered 3 inches from middle in the front I put the finnex and the aquaticlife was staggered 3 inches from the center on the back. When I took individual readings the sensor was directly under the light and for combined readings the sensor was in the middle.
