Hey all, weird question!
Does anyone know any chemical reaction that would allow plastic containers to absorb NO3 over about an hour?
I test my water at home and get NO3 at roughly 26. Some mornings I don't have time to test before work, so I collect a sample in a small Tupperware and bring it to work to test (work at a LFS.) The water then tests at roughly 12, after about an hour of transport in plastic.
Test is preformed with the same Hanna HR NO3 checker. I have rechecked both times this has happened, and the results are the same. This happens within the same day, as in;
Test in the AM at work, test reads ~12
Test in the PM, straight from tank, test reads ~26
Thanks for any input!
