Within 24 hours of dosing half the recommended dose of RedCyano RX, I have killed all the fish in my DT except for the bellus angel. When I got home for work the cardinal, firefish and royal gramma were dead. I did 33 gallon waterchange and returned the skimmer and GAC. Then I watched the yellow tang, three anthias, foxface, red velvet wrasse, pink bar wrasse, yasha haze goby and blue tang die slowly. I'm just devastated, I should have followed my gut. I never trust products like this and for good reason. The tank is really beating me down right now.
My corals are all PO'd, limited polyp extention. One branch of the sunset milli RTN and half the Hoeki RTN but otherwise SPS are hanging in there.
Im in damage control right now and will be doing mass water changes over the next week.
