My nitrites levels will not come down!

Let me start off at the beginning of this story. I was fish less cycling, my ammonia was going down to zero everyday after adding ammonia, my nitrites weren't quite at zero but very close. My fish were arriving in a few days and I knew I was cutting it close. So I did a water change, and after that my nitrite levels spiked! Off the charts, with no explanation. My tap is zero for everything except ammonia(chloramines) so I don't know why this water change would have cause such a spike in nitrites when I was adding clean water.

Anyways cut to now, I have my fish and since the tank still isn't 100% cycled I'm doing twice daily water changes, small amounts about 15% each time with a total daily water change of about 25-30%. My ammonia still looks good at zero, but nitrites are still off the chart, even after each water change the number never changes at all.

Is this normal? I tested the solution on my tap and got zero like always so I don't think the test kit is faulty.

Do I need to do larger water changes? I'm using half a cap of prime every time I do the water change. The fish seem fine, so I'm hoping if the nitrites really are that high then at least they are neutralized.

Please help me figure out why my nitrites are not falling and how to bring them down.
 
You haven't finished cycling if you are not showing nitrates . .ammonia spike then nitrites show up then nitrates.. nitrites will keep spiking until nitrates show up

I have all ready been showing nitrates too, before the very first water change they were around 80ppm
 
As long as you have fish in there , there is ammonia being added to the tanks... so nitrites will keep spiking.. the water changes will help
 
Ok,, you didn't say that earlier but even so just by showing nitrates it doesn't mean you were done cycling

The other thing being us that it's possible the test is bad
 
I am questioning the nitrite reading, ammonia 0, nitrate 80ppm. processing is happening. with fish in no longer a need to add any ammonia, what test kit are you using?

I'm using the api master kit, I didn't think the test was wrong since when I test my tap it comes out zero. My next thought was to test the water Ive added the prime to before it goes in the aquarium to see if that could be giving a false reading.

Since I've got the fish i haven't been dosing with ammonia, just doing the twice daily water changes, nitrates went down to about 5-10ppm, but the nitrites are always really high.

Maybe I should get a second test to confirm.
 
it well not hurt your fish to do a 90% or fin level water change, do that and nitrite still though the roof, its the test,
 
how are you changing your water? water change system like a python? or buckets.

Using a python to siphon the water out but adding water with a bucket. The PH straight out of my tap is a lot higher then after its settled a while so I like to add it to a bucket with an airstone and prime for a little while before I add to the tank
