LF PAR Meter

[straightrazorguy]

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?
