Cycling Tank

I am having no luck with my numbers lowering.
I have no fish in there only a sponge filter and a heater thats set up to 84.
Ive been cycling for over a month now.
My nitrates have been super high for about 2 weeks now. Doesnt seem like my nitrites are lowering either (they dropped a bunch within the past 3 weeks as it was super purple but since then nothing), if they are lowering I cannot tell & im dosing ammonia every time it drops to 0, adding just a bit for it to reach around 1ppm or slightly over.
Top picture is today
Bottom is over 2 weeks ago.

 

What are you dosing the ammonia up to?

 

Im dosing up to about 1 ppm of ammonia or slightly over.

 

I had to do a few 50% water changes to knock down my nitrates, and once that happened, my cycle finished. I was dosing up to 2ppm ammonia as well.

 

Wow thanks, im going to try that because my nitrates are off the chart, its ridiculous. I figured it would need a little help. Thanks so much

 

How often are you dosing ammonia?

 

Im dosing every time it drops down which is like 24 hours.
This is the 3rd water change I've done. 50% of it and my nitrites are at the same number. I dont know what im doing wrong
