    Hey guys, can anyone please help.
    I bought one of red sea's new nitrate/nitrite test kits & there is some major problem on the instruction sheets.
    On the leaflet, it says to mix as directed & then take reading immediately, but not later than 1 minute.
    On the colour chart, it says to mix as directed & then to wait 9 minutes before reading colour.
    So i tested both ways.
    #1 immediately - it showed no colour at all. But on chart, it says that 0 nitrates should be light blue.
    #2 left same test for 9 minutes, & it turned a bright red which indicates 50ppm nitrates.

    I then did both tests with ro water & got exact same results.

    Can someone please help, ive always liked red sea products, but this is a bit SUBSTANDARD!!!

    Test kit photos

    Ok, just to clarify, this is the same for the NITRITE & NITRATE test. Both indicate different times at which to read the colour from the enclosed leaflet & the back of the colour charts.
    In both the cases, when i read the colour immediately, it shows absolutely no color (supposed to be light blue for 0) & both show extremely high nitrate/nitrite after 5/9minutes.

    In this photo, i used RO/DI water to do the nitrate test, left it for 9 minutes, & shows 50ppm nitrates.

    Please comment/help if anyone knows how to use these kits.

    Hi @brentnorm, thanks for the reply, are you using the new type.

    Here is a pic of the one i bought.
    I took it back to the petshop where i bought it & they only said that i must have changed the card out with an old one, but ive never owned any red sea test before...

    Oh, yes ive seen that one, actually looks like a very nice kit to have, lol.
    Will see what i can find out about these tests.
    Was actually hoping one of the sponsors that stock these can give me an answer/indication on the problem.
    Thanks again @brentnorm.
