Up to this recent ICP test that showed some low trace elements( the test that made you start dosing trace elements), all PRIOR ICP tests were fine?Not sure what’s going on here. My tank is nearly fully automated and runs a CALrX. The only change is dosing Tropic Marin trace elements after an ICP showed my trace elements were low. One of my largest colonies is nearly completely gone and covered in algae now. It started with paling out and then browning tips. The adjacent coral is started to retract and pale on the tips as well. I’ve lost three other colonies in the last two weeks.
The tank is super stable - 8.5 dkh, 450 calc, 1350 mag, 15 ppm no3, 1.026 sal, 78 degrees.
I did a 60 gallon water change a few days ago and have seen no difference. The LPS in the tank seem to be completely fine.
I’ve been doing this for years, and this is one of the few moments where I’m truly stumped…
