Nitrites And Nitrates Increasing Simultaneously

    Hey everyone!

    I've been cycling a new tank with substrate from my established one. My ammonia levels have spiked and are almost done falling. A few days ago, both my nitrites and nitrates began to increase. They're still both increasing today. Is that normal? I thought that nitrites were supposed to spike first and then drop as nitrates rose. I'm just curious if anyone has experienced this before and if you know anything about it.

    Thanks! :)

    I am not with you.....are you not using a filter like a sponge, HOB or canister? Are you using and under-gravel filter? What is the point you are trying to make by referring to using substrate from an established tank?

    btw @Roger121 has given a GREAT diagram to understand how the phases in the nitrogen cycle kick in and kick out - worthwhile understanding it to visualize what you are trying to achieve - the process is dynamic, so a single snapshot does not tell you where you are in the cycle.

    If you are beginning to get nitrates you are almost there. Keep up with water changes frequently . Your bacteria should catch up soon and your nitrites should go down.

    I think the op was just letting us know they seeded their tank

    Thanks everyone! I've cycled a few tanks before but this one is different than the others. I was just curious.
