Target feed it too, to keep it's energy levels up.  Without the algae internally, it will not be photosynthesising, and producing sugars to feed itself.

Put the coral at the bottom of the tank and near the edge where the light intensity will usually be lower. Also consider reducing the intensity of your lights especially uv if you have a programmable setting for uv.

The reason for bleaching is that the micro organisms living inside the coral which photosynthesise die off under too too high light intensity. As long as some remain alive and you reduce the corals exposure they will reproduce and the colour will come back.

Yeah seems to be since changing my lights thinking about it. Any suggestions?

Just seen this thread:

That's most likely the issue.

Yes, it worked.

Have you had temperature fluctuations by any chance?  Are your other parameters all in check and stable?  What about increase in lighting?

Almost the same, but collonistas will be the lighter colours, and stay that size.

Can you do a video on your phone of how you have it set up?  Show us the weir, drain pipes in the weir, then the sump and how the drains feed into in, the return pump and pipework, and the ATU.  It could be all sorts of things, but this will give us a clear picture - it's probably something simple we can identify for you.  Post the video to youtube, then post the link here.
