Nh3 and nh4 low but not gone

[TwentyfiveCents]

I'm about 3 month into my first tank picked up the seneye reef and it shows my nh3 is at 0.001 and my nh4 is at 7.3....I know nh4 is not a huge concern but is it possible to get nh3 and nh4 to 0.000?

Thats well within the margin of error..
Assume its zero and never look back..
While we say zero around here the whole "waste" process means that you must have ammonia and it must turn to nitrites and then to nitrates.. Its just doing it fast but its still there at all times..

Thats the problem with fancy test systems like that.. Sometimes more data is just too much for some to handle Ignore it..
