Hahaha..bro Gouldian, you are not alone..my 3ft tank crashed too on Tuesday. The symptom almost same as your but I never bought any corals from reefers nor LFS this few week instead doing more fragging of my zoas from my 3ft to my nano tank.
Currently, 3 clown fishes, anthias, fire shrimp RIP n SPS like milli, BIrdnest bleached too.....sigh! N make thing worst, my Radion led lightest failed me one day after the tank crashed...sigh, sigh, sigh..!
Will it be palytoxin poisoning too?
