no I wouldn't. we kicked up a thread explaining why nitrate and nitrite tests are useless for cycling. only ammonia matters, and time underwater. you've met those, so its done. you can continue to cycle for additional weeks though, it wont harm a thing. things that can affect nitrate are presence of denitrification, test drift etc. its for algae tuning only, the reason why is no other mechanism other than nitrate production exists to lower ammonia in an aquatic system with submersion history and these markers in place. its being produced, whether or not its gassed off, too low for you to read before an actual bioload and detritus is in place, ranges tank to tank. we don't use it for those reasons.
