I've always found API to be more then accurate and consistent for me except for pH and PO4.

Welcome. I hope it helps and it was very informative for me to go through this exercise.

Yeah, I was really hoping since AquaMedic took over AWT and says they upgraded with all new lab equipment they would have been somewhat more accurate. I don't think they were even in the ball park with some of those results which was rather disappointing.
I might look to do another Triton test in a month or two after not dosing anything that I just introduced. They may be worthwhile just out of curiosity once or twice a year.
The Tin reading really threw me off. The zinc I can see coming in with the algae sheets or food I feed but that had a pretty decent drop in levels so I don't know. I've seen 3 other people now having high Tin levels just recently as tested by Triton so I'm not sure if they just had some kind of interference. 2 on this forum including me and 2 on other forums. One person on the other forum actually had multiple readings from Triton over the past year and it was reading 0 tin levels up to just this past weeks reading.
