I sent in a sample of my aquarium water not the spectracide.My question was more specifically what did you prepare that sample you sent to triton. Did you make a 1ppm nitrate solution? Did you do a 10 ppm solution? I ask because if you did a low concentration solution, the contaminant might be at low enough levels that it couldn't be detected by the IPC-MS, but as you are dosing that to your tank it builds up. Analytical assays have a limit of detection and a limit of quantification. Another thing to think about is that it is possible that the IPC test is tuned towards testing sea water samples and if you submitted a potassium nitrate solution in RODI water it might not be able to assay correctly (not something I have confirmed with triton to some assays are matrix sensitive).
