    ive started a 30 gal tank and currently 3 weeks in on a fishless cycle, ammonia is down to 0 ppm, nitrites are 5 ppm and nitrates were 150 ppm. After two water changes within 48 hrs i got my nitrites down to 2 ppm, my nitrites are right back up to 5ppm and my nitrates are at 40 ppm.
    I've added ammonia twice since starting and have gotten the bacteria to process ammonia within a 24 hr period. I've also added dr tims twice. Did I stall my cycle?

    I haven't dosed ammonia in a week. And nitrites are still 5ppm+ and nitrates were 150 ppm before my 75%water change. Nitrates now are currently at 40ppm. Should I dose prime to help bacteria with nitrite spike?

    Hi, welcome to the forum :)

    I would do a huge water change, enough to get nitrites back down to less then .50.

    Dose ammonia at that point only to 1.0 and then check your levels in 24 hours and let us know where they're at.

    You have the right bacteria, just not enough of them yet.

    I dosed seachem prime to help the bacteria. Got the nitrites down to 2ppm. Will check the nitrates tomorrow to see if the nitrite was processed, or slowly being processed.

    Thank you.
