Clean up crew doing good but i have lost clowns

Not sure why this happened, could it be that introduced when i changed water?
Im not ready to put new fish any time soon until i figure out what happened and make sure it safe to put new fish.

When you say you treated them for ick, you didn't put medication in the display tank did you? Most ick medications are copper based which is highly toxic to corals and absorbed into the rocks and sand.

Yes i put medication in DT, the tank is pretty empty i have only green bird nest.
I have no idea that ICK medication so toxic for corals. I will do more water change and wait at least a month or more before introduce new fish to the tank or any corals.
What is scares me that white spots appears overnight and it was all over clowns, not just few spots.

@rishu_pepper it would be nice if i can get some corals from you but it would be after some time.
