Hello everyone! So I’ve been cycling my Fluval V 5-gallon tank for the last 11 days and everything has been going pretty quickly. I have been using Fritz ammonia for my fishless cycle and the ammonia phase went pretty fast! I also put some seeding from my other tank as well into the cycling tank which definitely helped cycle it quicker. However, I have reached a point where my nitrites are so high that they seem like they aren’t going down. My nitrates have definitely climbed up each day but my nitrites have stayed the same for at least 4 days.
Should I do a water change? If so, how much of a water change? My tap water is already dechlorinated so do I have to add prime to the new water? If I do that, will it make the nitrites and ammonia in my tank virtually non-existent? Attached are some pictures from my test this morning. I did add enough ammonia after I tested it to bring the amount up to 0.25 because I know that without ammonia the bacteria will starve.

My aquarium is set to 79 degrees (I would make it hotter but I have plants there and I don’t want them to die), and I have a large air stone in it as well.

Does it matter to you whether your fish are captive-bred or wild caught?
