Yeah first thing I noticed is salinity at 1.020 .
I've left my torch skeletons in tank after they died,not because thought they come back to life,just to remind myself I've tried 3 now and longest they lived is 3 months so don't get anymore.
Not sure If it was my tank not mature enough or they was wild torches which I read often don't do so well .idk
well, pray for something else but not for this miracle brother.
Before adding more corals please check your parameters or I guess more corals will end up dead.
