LF PAR Meter

[straightrazorguy]

I am having some chronically bleached corals, so I would like to borrow a PAR meter for a day. I'm in New West.

Is it low nutrients causing the bleaching?

I suspect it's the light levels. The corals I'm talking about are green slimers and Red Planet mostly. They are bleached (colour very faded) on the upper side, and have more colour elsewhere. Yet, other corals have great colours.
Is it low nutrients causing the bleaching?

Thanks Galizio!

My parameters are too high rite now and my smaller frags are bleaching.
And dropping my nutreances too quick I'm told will fade the coolers too

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?

Thank you J&L!
