I read a bit further and the products state that
ammonia and
Nitrite testing will still be positive.
So it seems they render the
nitrite harmless and does mess up testing.
The problem I see is knowing what percentage of the tested molecule is toxic. ie. You test 10ppm
ammonia. Maybe 100% of it is bound or maybe only 60% is bound with 40% toxic.
I kept adding a little each day because I knew my filter was not up to speed yet.
