What is your rate of increase/time for coral acclimation to LED lights

[homegrowncichlid]

Hi,
Just realized that I'm taking too long acclimating new SPS corals to my SBreef lights.
I picked up some SPS frags, 2 weeks ago, acros, birdsnest and poccilliporas, and set my blue LEDs at 30% and whites to 15%, which would be ~100 to150 PAR for a week. On week two, I raise blue to 35%, sill sub 200 PAR and now on week three, I moved it to 40% just hitting ~200 PAR. My target is blue at 70% and ~300 PAR, but at this rate of 10% per week, my millipora, and acros have lost tissue on the base by week 3, so I'm assuming I'm talking too long to too acclimate.
What is your rate of increase? so for me,10% per week is too slow, or I'm starting too low at 30%. Thanks.
Should I be increasing more frequently, ie 5% twice a week? or even faster at 5% every other day?
I've burned some SPS in the past and also turned them brown, by bringing the intensity up too quickly, so I really have no idea.

What is your parameters . Should be no problem with the light

I usually do an overall 10% a day (aka not individual channels, just the main intensity for the Radion), starting at 50% down from my usual setting.

Do you guys do this for every new addition? Sounds like a pain and causes issues for existing coral?

I do this only if I have more than a single coral. Otherwise I just bring them up slowly (since I know what my PAR is at different levels).

i doubt its the light causing that

I just throw them in and hope for the best...w

So you bring you lights down to 50% and raise them 10% a day and they are acclimated within a week? I've been moving them way too slowly then.

Just took a look at the frags this morning, the birdsnest and pocilipora are faded but intact. The orange digitata, which I know can go high light, never extended its polyps. And the 4 acros, millipora included, also never extended their polyps and are the only ones that have lost tissue. Patchly white skeleton exposed, within one day, this past Saturday. Which is how I knew something was wrong.

Perhaps a better question, is how do I know if a coral is not getting enought light? Do they extend or not? On the otherside, how do I know if a coral is getting burned? They turn brown and do not extend polyps?

Yep a week overall. Unless obviously I see them stressing out. Then I will lower then in the tank and move them with their own time.
