I've got a test stick by TetraAqua - The 5in1 stick.
I just tried it. It reads zero nitrate and nitrite! But 10ppm in NO3 is
impossible to detect in a test stick.
I've also got a TetraAqua - 6in1 stick (only a month old) and that also
reads zero on NO3 and NO2!
I've got a unopened API Nitrite test kit I bought 2 weeks ago, no date on it
anywhere. But its new, I gave that a try and got: zero nitrite.
So I retested with the original API test and still got zero nitrite!
So there was 10 hours difference from the NO2/NO3 test I did this morning
Morning - NO2 : 1ppm, NO3: 10ppm
Evening - NO2 : 0ppm, NO3: 5ppm
After I did the morning test I threw in half a tablet. I can still see the
half lying in the bottom of the tank virtually undissolved.
(BTW, I discovered that the 500mg Calcium carbonate indigestion tablet
contains 615mg of Sucrose.)
So I guess this must have triggered the sudden nitrite reduction?
Now, I'm just confused.
