Has anyone had an issue with their Salifert Nitrate test kit? I just got a brand new one today and just about had a heart attack when it said my nitrates were 50! My Red Sea Pro and my old Salifert test say it's below 10.
This test kit has a new color comparison card but the colors are close to the old one IMO. I've retested 3 times and get 50 every time. There is some precipitate in the bottom of the vial with every test. I've never seen that before with this test. Any rumblings of people having similar problems?
