I'm really perplexed. I started cycling on April 20th. I added pre-established 38 ceramic rings, 2 sponges and 250ml of Seachem Stability in my 40g with temp at 80F. I started off with 2ppm ammonia and I haven't added any since
to not make the nitrites sky rocket. April 23rd there was 0.25-0.5ppm nitrites. Since April 25th, my nitrites have been off the chart purple. It looks like 5ppm on the chart but when I dilute the 5mls into half tap/half tank water it reads 5ppm, so it must've been over 10ppm nitrites.
Yesterday I did a 50% water change: nitrites didn't change but nitrates cut in half (they were 80ppm+).
Today I did a 50% water change: nitrites didn't change again, still reading 5ppm+.
What do I do? Leave it? I can't add more ammonia because it'll make it sky rocket again. I didn't want my cycle to stall due to the super unceccessary high nitrites. It obviously processed alot of nitrite if my nitrate was deep red a few days ago. I don't understand how I can change 100% of my water yet the nitrite hasn't budged? There's nothing in my tap water that would contribute to this, everything is 0ppm out of the tap. I'm using the API liquid test kit.
Right now, after doing a second 50% water change:
