I see a purple blob

It is a very close picture of a rock and the purple is open water behind it lol it’s the little white things attached to the white rock I’m worried about

I have already removed the small coral stone from the tank

If you've removed it - its gone... I would rinse and scrub the stone and put it back

Whatever was on that stone is going to pop up (probably) - on other stones.
