Possible ICH outbreak

[HarleyC]

Thanks.
They appear to be acting normal and although there is still some faint white spots on a couple, most has gone. The Niger Trigger had a few under his jaw, but these look to have gone. They are all eating okay. I will monitor. It is a whole system transfer yes. Nitrates still high. Was going to wait until Friday and do a 20% water change. Corals etc. are all looking healthy and other parameters are testing fine.
Appreciate the advice.

Is it possible that what you see is some white grain of sand stuck on the fish? when I move some of my sand it sometime stick on some of the fish and remain for sometime all day, then it's gone. Especially my niger trigger get that from time to time because he's got a cave and dig in the sand.
