Dricc
Great call
The first sentence we covered in our reef cycling thread was to not test for nitrite, ever. Save the headache, the misleads
Just for those kinds of reasons. Prime water conditioner is a huge false positive nitrite cause, we simply don't even need to know nitrite data. Not even during dry surface cycling, nitrite isn't needed to know in reefing.
Perhaps in medication/ hospital tanks. Past that, nope. Aquaculture and production level bioloading is different, home reefs don't generate nitrite after maturation given accountability for all fish, no meds, and no sourcewater input and no huge organic waste stores in the tank. Has to be a false point of sale unless one of those, imo.
