I Think My Aquarium is Cycled?

    Hi,

    It's been about 6 weeks since I started cycling my 5 gallon aquarium w/ 1 betta and 1 snail (who just died). On 7/3, I had the biggest spike in numbers:

    Ammonia 0
    Nitrite 3-5 (very hard to discern on the color chart)
    Nitrate 20 ppm

    Then I did partial water change since it'd been 2 weeks (Prime) -- Numbers dropped a bit, but still showing on the way to cycling, and was at these readings for about 5-6 days:

    ammonia 0
    nitrite 1
    nitrate 5.0 ppm


    Today:
    Ammonia 0
    Nitrite 0
    Nitrate between 0 and .5ppm (3 tests: 1 at 5ppm, 2 at 0)

    So what's going on? Is my tank cycled and just really clean? I'm confused by the super low to non-existent nitrate reading.

    You need to bang the #2 bottle real good. There are crystals sitting in the bottom that you need to break loose.

    Okay, will try again. I shook that sucker hard! But I will try banging on the bottle. Thx

    Just did another test:

    Ammonia 0
    Nitrite 0
    Nitrate 5.0 ppm (just barely, slightly lighter orange than the card)

    So do you think my tank is cycled? The nitrates are low., but they must be enough as ammonia and nitrite are at zero?

    Looks cycled, when was your last water change?

    I would think so. in that 0-0-some nitrate indicates a cycled tank. All the best, rick

    Thanks Rick and Dom :)

    Yep with a nitrate reading of 5 and your last water change was 2 days ago, sounds about right.
