20 Gallon Tank Nitrites won’t go down

Dan12boy

Okay so I’ve been cycling my tank for about a month now and everything was going smoothly, had an ammonia spike for al little while then took care of that and then the nitrites shot up for like a day or two. Kept doing water changes but it stayed that way, my ammonia then went up too but after some days went back down. My nitrites though haven’t gone down whatsoever. I’ve been doing at least 70% water changes for the past couple of days since the spikes and then about an 85% water change yesterday but checked today and it’s still the same. Did another 70% today but I feel it’ll be the same. I added floating plants and hornwort a couple days ago and the day after adding was when my ammonia went back down to 0. I’ve had some water wisteria in for a couple days too but I don’t think they’re really doing anything yet. My nitrites have been about a constant 1.0ppm. All I have in the tank are 6 guppies, 3 adult bladder snails and a couple little babies. That’s it. Except for detritus worms which I think were introduced from the floating plants but I only see them when I gravel vac which is almost everytime I do a water change. Any advice or help would be helpful. I added some pics from when the ammonia began to go down up to today. Each picture is a different day. I can’t buy anything as I’m super low on money and I’m just getting a job that I don’t start for a while.

For now I would stop vacuuming the gravel. Give the bacteria a chance to get a good foothold. When you do your water changes simply remove and replace water. Don't clean anything in there. Detritus worms aren't hurting any thing and are often in a new tank. Most folks do experience them for a while. Try not to overfeed. If there is food left over it is feeding the worms. Give the tank time to get settled in and I suspect you will see the last of the little critters.
