    Do you mean, the new light has been running for 24hrs....or your photo period has been 24hrs?

    What lighting were you using before? You may need to dial back the light even more and slowly increase it over a few weeks...say 10% increase per week. Also how high above the water is it suspended?

    Go down to 25% and come up from there.

    If you're corals are hurting, then I'd probably increase slower than 10% a day...just so they have some time to recover and acclimate slowly.

    12 hours is probably a bit too long btw. Do they run full intensity from 10 - 10?

    It is a dry heat, yeah right !
    I do not have LED so I have no clue what I am talking about, BUT further decreasing the intensity and also decreasing the photo periods seems like a common sense intervention at this time.

    What types of corals do you keep?
    Specifically how to they look worse, closed, shrunken, coloration...?
