Emergency advice

[DonCorsean]

So I'm freaking out right now. I've been working on a new build which has been running or about 2.5 weeks right now. I planned to slowly move livestock from my old 55gal tank. Over the past 3-5 days I've had 2 sps die that I've had for almost a year and now my favia and another sps appear to be sloughing off flesh. I've checked params ammonia, nitrate, nitrite, ph, dkh and
calc and all is good.

I just did a water change and will do another over the next 24 hrs.

I don't want to move stuff into the new tank as it's so young, but I'm worried about losing any more corals. All the fish seem fine.

Any advice?

what have you changed? or slack on by working on the other one?

Just moved a few small pieces of LR and a chromis to the new build, I'm debating moving more over...

You did not kick anything up did you?

I would also wonder if you stirred up anything when moving the rock.

It's possible, but params are ok. So just do bunch of water changes or should I move things over. New tank params are ok as well. I would have thought it would still be cycling.

If you move established live rock directly from one tank to another you won't see a cycle. Just be sure to shake off detritus in a bucket of tank water. Move all livestock over before you stir up anything. And I'm sure you know but if you are going to reuse your sand you have to rinse it very very well until the water runs clear. This worked for me moving from a 55 to a 125. HTH
