Hey guys, I had been doing a fishless cycle for a few weeks on my 55gallon with no seeded material. About a week ago one of my coworkers agreed to put one of my filter cartridges and one of my bio wheels on his tank to get some bacteria growth on it and yesterday I added that material to my filter. I quick added some ammonia (I didn't measure how much I just dumped some in I'm pretty sure it was way more than the recommended 2-4ppm but I was in a hurry and didn't want the bacteria to die without food). About 9 hours later I came home and tested the water, 0 ammonia and over 40ppm Nitrate. Previous to getting the seeded filters all I had was ammonia and 0 nitrite and nitrate. So after I tested and got 0 ammonia and high nitrate I didn't have time to do a water change so I just added some more ammonia and left. This morning I checked my water and I have very low ammonia, around .5ppm, off the charts nitrite, and very low nitrate. How did that happen? When the nitrate level was way up there I figured my tank was cycled I just needed to do a big water change and then add fish. Now the next day I see super high nitrite and almost no nitrate, even though I didn't change any water. Any thoughts? Do I just need to do a big water change and see where I'm at?
