Yes, NO2 is for Nitrites. A new system it is NO2, as NH3 is oxidized to NO2, which its
then oxidized to NO3
What ever kit it is, is it measuring it as NO2 or N-NO2 or if you mean a Nirtate kit, is
it as NO3 or N-No3....... BIG difference here. Most get very confused here when giving
tank NO3 level, as 5 ppm N-NO3= 22 NO3.
The difference between these measures is not difficult to understand, but itcan cause a
lot of confusion because it is often not obvious which measure that a particular reefer or
author refers to. The bottom line forthose who want to know the details:
[N-NH3] (ammonia-nitrogen) = 0.8 [NH3] (ammonia ion)
or
[NH3] = 1.3 [N-NH3]
[N-NO2--] (nitrite-nitrogen) = 0.3 [NO2--] (nitrite ion)
or
[NO2--] = 3.3[N-NO2--]
[N-NO3-] (nitrate-nitrogen) = 0.23 [NO3-] (nitrate ion)
or
[NO3-] = 4.4 [N-NO3-]
The conversions between the scales is easily derived as follows:
mass of the complete ion
[ion] = ------------------------ [nitrogen-ion]
mass of a nitrogen atom
And clearly 1 over this conversion factor is used when converting ion concentration to
nitrogen-ion concentration. One can reproduce the above numbers with this formula and
the following information.
Masses:
To within a percent, we can use mass of a hydrogen atom (H) = 1, mass of a
nitrogen atom (N) = 14, and mass of an oxygen atom (O) = 16.
Chemical Species Formula Mass
Nitrate ion NO3- 14+3*16=62
Nitrite ion NO2-- 14+2*16=46
Ammonium ion NH4+ 14+4*1=18
Ammonia molecule NH3 14+3*1=17
Thus thus for 14 for N-NO3 and 62 for NO3, so 62 / 14 = 4.4 or 1 ppm N-NO3 = 4.4 ppm
NO3

Actually, we test for amonia and nitrites when cycling tank
and then for nitrates when the tank is stable already...
BTW - most tests for nitrates work the way they first reduce
nitrates to nitrites and then show the level of nitrites.
This is the biggest reason of failure measurments of nitrates when
tank is cycling and water contains significant amount of nitrites. |

If using a kit labeled *freshwater* is ok for *salt water*.. why do they
make different kits for each then? Some specifically say *not for use in..
fresh.. salt..* whichever. Is there really no difference?? Not trying to be
difficult, I just really want to know if there is a difference or if the
companies just try and expand their sales by labeling them differently for
the same thing.. and charging differently as I sometimes see...

i do know that some nitrite test kits do both, and use the exact same color scale/chemical
amount ... in both salt and fresh, in fact all 4 nitrite test kits i have do work in both
fresh and salt, and are labeled as such.
i think the salt only or fresh only applies to certain ways of testing, and certain things
one cant really test for in a sw aquarium like GH, i dont know of a single GH test kit
that works in salt water, and as i understand it the test kit works it just pickes up the
calcium in the water and it makes the values in effective.

Boomer..... I am getting a fat heache after trying to consume those

Boomer,
You do realize that I'm over here giggling like a lil' kid as I scroll down through more and
More *and* MORE Chemistry info from you.
Thank God someone is keeping track of these important issues.
Marc, giving you a hard time.

This is true and in some kits high levels of nitrate can cause interference with Nitrite
tests

"Thank God someone is keeping track of these important issues. "
Well, someone has to keep an eye on misinterpreting or not understanding things. For
example, do you have a refractometer and if so are you correcting it to seawater ? In
other words, if your refract is converted to salinity and it comes out 35 ppt, that is not
equal to 35 ppt seawater  Not to mention those using 'clinical refracts' which are on a
different scale, giving worse readings

more likely what do you call high nitrates?
my ap test kit is a cyan color for 0 and does get effected by HIGH nitrates
