    Hi all,

    First post to these boards. I'm currently setting up and cycling a 37G tank with a Fluval 206 canister filter, heater set to 80F, and minor aeration setup.

    I'm utilizing Dr. Tim Ammonia Chloride, and also included One & Only the first day of cycle. Within a few days, the Ammonia dropped from ~3ppm to 1ppm, so following the guide I dosed up to 4ppm again and waited. However, it seems the Ammonia has now stalled, as its been 4 days and it hasn't dropped at all from 4ppm (whereas before it dropped from 3 to 1 in a few days).

    Here are my current parameters on Day 7:
    Ammonia: 4ppm - has been constant for 4 days
    Nitrites: 0.25ppm - has been constant for 4 days
    Nitrates: ~20ppm - has increased somewhat since Day 1
    pH: 8.2 - has been constant for 4 days
    Temp: 80.2

    Here is the Fishless Guide I am following: http://www.drtimsaquatics.com/resources/fishless-cycling

    Here is the ammonia I have used (two doses so far): http://store.drtimsaquatics.com/Ammonium-Chloride-Solution-for-Fishless-Cycling_p_190.html

    Here is the One & Only bacteria that I used on Day 1: http://store.drtimsaquatics.com/one-only-nitrifying-bacteria.html

    Would love to get some advice/help: it seemed like after day 2/3 the cycle was going to be pretty successful and fast, however this hiccup has now stalled it through a few days.
