Hey guys, my tank finished cycling a little bit ago, like, 4 days ago. The past 3 days it had a 0 reading for ammonia and nitrite, but this morning I measured it and I had 0 ammonia, 5-10 nitrates, but 1-2 ppm reading of nitrite! I quickly did a pwc of 20%, but now the nitrites are reading at 0 ppm. I am currently treating that tank with primafix and melafix, as a few of my corys have torn fins, and 1 potentially has a fungus growth. I also did treat that tank with sea chem flourish yesterday for my plants. Its a 5 gallon with 5 corys in it *they're in quarantine, I don't plan on keeping them in there* with 3 bunches of anacharis plants. I also did a gravel vac today. I have been feeding them 2 times a day, with 3-5 sinking hikari discs each time as they pretty much devour all disks within 10 minutes. I did remove 1 bunch of anacharis however, as it seemed as if it was slowly dieing. Anyone might know why my nitrites jumped up so high with 0 ammonia reading and 0 nitrite reading just yesterday, and after just a 20% water change the nitrite reading is back down to 0? Could it have been a false reading? Thanks!
