What is PAR?
Does PAR help with coral coloration i.e the higher the PAR the more the coral will color up?
I am running a Ushio single ended 250 watt 10K bulb and was told the XM 10K bulb is better because it has a higher PAR rating.
Are there any PAR studies that have been done on bulbs that are on the market and if so where can I find these studies to compare which bulbs are good and which may be crap?
