Re: Red Sea vs Tetra nitrate test kit


Do you have Red Sea Nitrate kit II.  If so there are 2
ways to measure nitrate, use the powder method.  This
is the most accurate of the 2 tests.

Don't feel alone.  I have had trouble with Red Sea
tests also.  And I
just tossed an old Wardley Nitrate kit that said my
nitrates were 10
times the level that my Seachem test kit showed.  The
Seachem Nitrite &
Nitrate test kit includes a vial of 10mg/l water for
validation purposes.
