So this weekend i had a precipitation event where my magnesium got so low my calcium precipitated out covering everything in my tank. Got all cleaned up. My mag bottomed out at 1062 and calc at 262 per my lfs and confirmed by home testing. My corals seem okay aside from the trach. Trach demise started a week ago, wasn't as puffed up as much as usual I'll say. Today I can see the beginning of the skeleton like where the mouth is. Both mouths seem slightly open as well. It's color looks good and hasn't bleached and reacts to light yet. My mag is now at 1400 and calc at approx 320. Calc has always been at 450 preceeding this weekends event. I guess my question is there any hope of it recovering? My nems look good, hammers, torch, few sps, zoas, everything seems fine except trach. Mag has been low for long time as i wasn't testing for it as apparently all the test kits are wrong and doesn't really matter, etc.
