Is it possible to have nitrites but no nitrates?

[mbarber87]

I am new to the hobby and just picked up some Hanna testing kit for the LR and ULR Nitrites. Both of them tested at 6ppm which seemed much higher than expected. I used the Salifert test kit to test Nitrates and it came back at 0. Same with Phosphates.

I don't really know what this means for my tank. Is this bad?

Other parameters that may be helpful are:
Alk - 7.4
Cal - 416
Ammonia - .25ppm

Tank is about 5 months old.

The hi707 (low range nitrite) and hi764 (ultra low range nitrite) report in ppb of Nitrite-N. Not ppm.
so 6 ppb of nitrite-Nitrogen is pretty small, and could be consistent (within uncertainties) with a zero Nitrate from another kit.

edit, I see you have measurable ammonia, so yeah. expect some nitrite, and eventually after ammonia drops the nitrite can drop and then nitrate testing will work properly.

Testing error. API for ammonia?

You have 0s across the board. Raise No3

Since the tank is 5 months old - either test error - of you need to figure out why you are getting Ammonia readings.
