racefan Posted May 30, 2009 Share Posted May 30, 2009 I have a Seachem Iodine & Iodide test kit.When I've ran 6 tests & they have all been zero(3 with aquarium water 3 with the reference fluid)the directions say "Reference value is 0.06 mg/l" seeing as how the reference tests are coming up zero makes me wonder if I have an expired test kit? The only numbers I can find are the SKU#00116 09780 then it says Mulit Test Iodine & Iodide 28290 Anybody know where to find an expiration date? is there one? Thanks,Mike Quote Link to comment Share on other sites More sharing options...
