I will be making a switch from my pair of 400 watt metal halides to LED's in the next week or 2. In advance of that, I decided to purchase an Apogee MQ-200.
My plan would be to measure par levels at various depths and postitions in the tank with the halides and then set the LED's brightness to similar or lower PAR levels to begin my lighting acclimation.
Can somebody give me some instructions on using this thing. I have the manual but in calibration, it doesn't mention LED's. Just Sun, flourescent and halide lighting for correction factor. I would assume I would treat LED's like halides but I am not certain.
From what I can tell, I should choose "electric" for calibration and "sample" for mode. Then use the correction factor for Halides to get close to the actual par number or should I forget the correction factor?
Any advice would be welcome as I have never used on of these things before.
The manual as it reads is not very informative. Especially as it relates to aquarium lighting. Its likely that I am complicating things in my head but some guidance would be appreciated.
