I have a big piece of rock with huge fuzzy mushrooms. They have been in my tank for about 5 weeks. Over the past few days mushrooms have been slowly dying. They shrink up, turn white and start to melt away. Any suggestions. Water levels are fine
High alk, high salinity and high light levels can be culprit's. Would be helpful to have actual parameter level's as well as and a bit more info about your tank....coral placement etc.
