i just received a Tropic Marin nitrate/nitrite test kit I ordered from Amazon. It looks like the expiration date is Sharpied out and newly hand written below in Sharpie.
Does anyone have a photo of what it should look like? I am going to complain to Amazon if someone altered the package.
I tested zero on both. I then used the Reagent D vial and it turned pink so the kit is working but I may have lost most of the test kit life expectancy, no way of knowing. Thanks
