				 PAR Readings 
 So, I went to J&L and borrowed the PAR meter.  I got the following readings:- Top of reef structure (6 inch below surface, where the bleached slimer is): 300-350, depending on exact position'0
 - Mid-reef (14 inch below water) 250-ish, +or - 20, depending on position
 - On the sand (23 inch below water) 100-120, depending on position
 
 What do the Canreef experts think of these levels?
