sir, ako din nagka mass RTN but peeling lang at hindi bubble form... i had added some new corals that had the beginnings of stn and it affected my whole tank after a few hours... i suspect na nakakahawa ang sps necrosis... kasi all my healthy older sps were affected... tapos skimmer is off pa. The dying sps must have altered water chemistry or sent chemicals through the water so i had to add carbon in case something in the water were causing the stn on older corals. Half of 4 new sps colonies died but 2 is better than none, necrosis of the other older sps also stopped after that... i opened my skimmer for two days just to filter out any dead sps matter that has spread across my whole system... after a week, ok na lahat so i guess sudden water quality change due to dying corals was the culprit in my case... so my solution was to get the water quality back to normal by fast physical & chem filtration (although water change might even be better sana)
another thing, unfortunately, i still have a few softies and even orange sponges which for sure sent out chemicals to attack the sps... (am planning to give away to any newbie willing to adopt red shroom and brown gorg) i noticed that even my photosynthetic gorgonian had a reaction so i quickly moved them to my sump for a few days...
about yung mg level, if wala kang test kit - indirectly you should detect the insufficient mg condition if your CA doesn't get up to 400 no matter how much kalk you add... if may skimmer ka taking out DOC, i think mg depletes given time... sa akin kasi, since off skimmer ko, super konti lang dosing ko ng mg
