Made freshly mix salt water but can’t tell if I have zero ammonia or .25 ammonia tell me what u guys think

The API test kit is a known source of confusion and is not reliable for detecting zero ammonia in a sample.

I came to say this very thing. API is know for this. its fine anyway. I still use API ammonia test kits to cycle tanks. just got to be aware.

but I am curious why are you testing fresh SW? are you using tap or RODI?
