Coral dip see if any pests come off
Try doing some extensive iodine dipping. Sucks that theres almost nothing you can point a finger on in this hobby. Youll just have to rule out probable causeI've searched everything. No idea how to proceed
Hey Sorry, did not read the entire story here but seems you still got issues.
My first checkpoint is to maintain No3 2-3ppm and PO3 to be lifted into 0.15 ppm range via Reef Nutrition Phytofeast. That takes only a few days ;-)
LPS dont like ULNS, and ALK higher then 8 burns all tissue while Nutrients are super low.
However, there might be a bacterial issue. For that watch out for whitish furry growing stuff in the low flow corners. Can also look stringy and the water appears a bit white or haze in the day looking along the tank from side to side. Also these non reef bacteria are limiting Coralline to grow. Watch for those symptoms.
Another issue might be a real contamination with heavy metals or something, for that I would preventively use a Triton Detox dosage for the tank. That requires activated carbon to strip it out, and here I would use Red Sea Reef spec to get all the crap out of the tank for once.
After that back to normal and see if things improve.
