My tank has been up for 20 years. Some live rock has been wet for 28 years. I got Dino’s when I tried sps for the first time six years ago. I’ve had them twice. Last time was about three years ago. I don’t know if they came in on the frags or corals. I notice that when I don’t have any green algae growing on the glass, it’s Dino time. My cure for this was stop water changes, turn off skimmer, and do nothing. I have since put in a fuge and use a smaller skimmer. I have some small patches of gha on my glass that I keep there as a monitor for nutrients. Feed more or less depending on the health of the gha. My tank is sps packed. Dino’s are no joke and it’s disheartening to see them destroy your corals.
So fast forward I had a copper issue with my ro unit. I was getting ati water test and my ro water had copper. My tank tested high copper so I broke out the Hanna and sure enough it tested .17. My corals were not looking good, but not dead. I also had red bug at this time, but did not know it for a few months so I’m not sure if this low level of copper made the corals look bad or not. Copper is an algae killer and I wonder if it could kill Dino’s at a low concentration. I do not know the lethal concentration for corals, but .17 did not kill any. I have sps, maxima clam, a couple candy canes and a hammer. This is something I have thought about for a while.
