Today's update- seems like the white growth / whatever it is has progressed. Just took this pic w a flashlight (lights haven't come on yet) and the top left seems to have gotten worse. Looking back at the pictures from Friday, it definitely seems to have progressed. This picture doesn't seem to capture it but there are more thin pieces / mucus flaking off the side and the facing the back of the tank (left side in this pic).
That said the other side of the coral is still the normal flesh color for the most part. This side probably gets the least floe per
@vetteguy53081 's point, weirdly.
Also noticed this white buildup on the crown, but that looks much more like typical mucus that is set to be, yet again, secreted.
I leave town Wednesday night until Sunday so trying to do what I can in the meantime- will definitely add fresh carbon before I leave just in case. Any thoughts based on the progression in the first picture? And any iodine supplements / dips you'd recommend? I've never done an iodine dip on coral before so not sure what to try and get on amazon, which would be most ideal in terms of it getting here before I leave. Thanks all, this is stressing me out but I appreciate all the help
