I made an error in dosing last night (well actually my error was falling asleep in between dosing a little at a time to recheck if I was using the right amount). Assuming I was using the right amount, which I checked twice before, I only dosed to about 3.0 ppm.
Tonight's readings:
ph 6.6, ammonia .25, NO2 0
