mini cycle no ammo

I think i am having a mini cycle. Nitrite and nitrate are very high. no ammonia. 6 month old aquarium. I already had my full cycle

Hi did you test after feeding your fish? Also have you lost any fish or anything that may have caused a spike. Uneaten food,large water change etc?

If your nitrites and nitrates are consistently high, I would recommend doing more frequent or bigger pwc.

I am guessing what ever it is, i have to change 15% off my water every day until it go down?

It depends on how high they are. How high is "high?" You may need to do larger water changes than that depending on how high they are. For example of nitrite is 1, you want to get it under .25, so you'd need to do around three 50% water changes to get them down. Ideally these would be done back-to-back. Doing them over the course of a few days just allows your fish to swim in toxins that could injure them.
