Neat info robbed from RC

Saw a post where a guy went outside with a PAR meter to see about sunlight... copy and paste below:

"Aprox. 15 mins ago, I went outside to see what amount of PAR our sun puts out. I usually think that 700+ PAR from a fixture is good for our tanks....but WOW....I wasnt expecting this.

Shade under a tree - 500-600 PAR
Direct sunlight at 4 pm in chicago - 1650-1800 PAR

My tank.....750 at waters surface."

Just thought it was good food for thought. Also proves PAR meters do exist.

I'm sure it's higher above the reefs, but how many reefs are only 2-3' deep max? I bet if he took readings from a few tanks here, he could pull some 1,000+ numbers.

Agreed... I was more surprised by the 600 in the shade.
