    API Nitrate Test

    The instructions say to add 10 drops of bottle 1, shake, then shake 2nd bottle for 30 sec and add 10 drops then shake the vial for 1 minute. Why all the mixing? Is it because of the viscosity of the reagents, or some other reason?

    Re: API Nitrate Test

    Not sure why but that test always shows ridiculous nitrates in my system. I have given up on it entirely. I have 3 other tests that show barely detectible while that one says like 80.

    Thanks Clint! I was just curious as to why it had to be agitated for so long.

    Re: API Nitrate Test

    Lynn, I remember you telling me that. The fact is my API shows lower than my Salifert! Color chart reading is very subjective indeed!

    Re: API Nitrate Test

    I found the api nitrates inaccurate also. Always at 80 like Lynn's. To be honest, If it was right most the stuff i keep would be dead at that level!

    Salifert is one of the better test kits with a higher degree of accuracy. However, reading a color chart is subjective.

    Re: API Nitrate Test

    I have an 'old' api nitrate kit that came with my tank a few month ago, and an new one that came in a new test kit, they both read the same; were readint about 10-20 until I got rid of my filter sock. Now they read 0.

    Re: API Nitrate Test

    Strange... I've used Aquarium Pharmacuetical test kits for years with no issues. I even duplicate test with Salifert along side when I doubt them. Salifert can get a precise (1ppm or 5ppm) on most test while the API gets close within 10ppm. Getting THAT precise is not necessary when I am on target.
    Make sure your kits are not expired.
    AP test kit's expiration dates...


    ..... each reagent bottle has a Lot # printed on
    the bottle. The last four digits are the month and year of manufacture.
    Example: Lot # 28A0102. This is a pH reagent manufactured in January of 2002.


    Ammonia, High Range pH, Nitrate, and GH all last for three years.
    Nitrite and KH will last for four years.

    Freshwater pH and Salt Level test are good for 5 years.....

    Re: API Nitrate Test

    Salifert for me. I also use Jungle 5-in-1 test strips ('cause I'm lazy). The strips aren't good for a precise reading, but they work good enough for you to know if you have a nitrate problem (if it's pink at all you have to keep working, if you don't have to strain your eyes to see that it's pink you have to work even harder). If the test strip and/or the Salifert is clear you are done with your work and get to sit back and enjoy. I really like the option for the 1-5 ppm range with the Salifert too.

    Good luck with the on-going battle of the nitrates!

    Thanks Woody,
    I have been complaining to Frank that my nitrates are reading way out of line. He told me to forget about it, b/c my clam was doing so well. I have been banging my head as to why my nitrates were reading at around 10-40 according to the api test. I figured there should be an expiration issue. It turns out my nitrate test bottle was made in 0104.

    With that in mind, what is the best kit to buy to replace it? I have heard that the powdered kits are the best.

    Thanks.

    Re: API Nitrate Test

    Salifert makes one of the best test kits on the market. I have heard the Elos also makes a good test kit, but I've never used it.
