Red Sea test kit readings

[Mr.Guy83]

Hello all,
My tank has been cycling for the past month.I have two ammonia Red Sea test kits, one is reading .2 the other is reading 0. Based on my nitrite being 0 and nitrate at 2-3 which ammonia reading is more likely to be true? Or do the other two have no direct correlation to ammonia? Chemistry wasn’t my best subject.

Is one passed the expiration date?

 

[Mr.Guy83]

Honestly I forgot to look. I give it a look tomorrow morning before headed out to work. That’s a good question

Did your nitrite go up and then drop to 0? If so, it's likely that your ammonia is also 0.

Yes, it did go up and come back down to 0.
Awesome! If that’s the case the cycle is complete
