Here are both of my results, ATI just came in. I haven't had a chance to really dig in as I am at work. One thing I will say is ATI's recommendations are lacking compared to Triton.
"ATI recommends
Tin is elevated, find source (corroding metals/magnets, RO water, salt). Adjust iodine dosage. PO4 is limited. RO result follow later."
Yep, triton pretty much suggest the same for Tin. 3x water change
