SPS acclimation to LED lights

[bsstover]

This may seem like a silly question, but here it goes. If corals are cultured under LED lights, do you still need to acclimate them in your tank to your LEDs (i.e. dim lights, shade, lower in tank, etc)?
I recently bought some new acro and two of the pieces are bleaching out whereas others are coloring up with good polyp extension.
Thoughts would be appreciated.
All other parameters are good.

When running most LED fixtures it is good to know where your hot spots are. These spots are where higher par needing acros can be placed. It is also possible those acros may be lower light acros.

Does you local club or anyone around have access to a PAR meter? I use one when I get new lights and make a PAR map. I have never had to acclimate any new coral to the LED light, I just use the map and place them in approx the same PAR they were in. Never had any trouble.

No one that I know of with par meter. I was under impression par is of little value when talking led light... Am I wrong?

I do like the idea of mapping out though. How do you know what par they were in at retailer?

Also have to consider how Long they were at the retailer before you bought them. Might be safer to light acclimate.

My achilles heel when it comes to corals and light acclimating them in my LED lite tank, is the Blue Matrix, I have killed this coral once before, and almost did it once again. I moved the frag back into lower light, Par area in my tank and appears that I have saved half of the already small frag. My frag appeared to be the encrusting part of the parent colony, that had about 7 sprouts coming up off of it. I saved 4 of the sprouts, so far. I know the lower Par sections of my tank and start all of my new frags in those areas for a few days, the Blue Matrix just appears to need more time, and then be placed in a lower Par of the tank, deeper in the tank, for a forever home.

Sorry to take so long for a reply. It's never a bad idea to acclimate, I have not needed to with a PAR map of the tank if I know what lights they were under from the vendor. PAR isn't perfect, but it's the best we have and does just fine with LEDs, for heavy blue the meters are off a bit, I think ~10% off the top of my head, but they are still really nice for LED lighting.

Some coral are really sensitive to lighting intensity, hopefully the coral vendor and tell you what ones, but really just watch them. I have noticed coral start to bleach, but if you catch them and move the coral then you can prevent it. Just keep an eye on the new coral daily and unless you go from really low PAR to super high PAR you can see if they need less light.

Thanks for response.
