Does anyone have a link where actual par numbers were taken from varying levels of a natural reef?

I found these and it deffinately helps.

He is pointing out that in Sprungs Coral Reference Guide, which is a bible of sorts, the light values he gives range from 1-10. If you use a factor of 100 for those values then you will get a pretty good gauge for par values. N

My PAR values are no where near those recommended, but my corals seem to be Ok. i am looking for values based on the the reflector, do you have a link for those?

I only looked at the first link, but I think its way off personally. It says Acropra should be 600-1000 PAR, most have it at 300-700 PAR. I'm sure that there are some even in the 200 range. Those numbers are a bit on the high side, IMO.

I agree, mine are in 300-500 range and I have one 560 hot spot right that not many things like to be in. I did find an answer to my reflector question. Just in case you wanted it.
