    Hi guys

    I started off a small nano (60 L) last friday
    I added RO water and salt.
    Then all the live rock.
    Today being the 4th day i did my first water test.
    I expacted to see a spike in ammonia but to my surprise...
    The amonia is at 0 and nitrite ia also at 0.

    I took some water to LPS and tested it there and they said the water is good.
    Im confused???

    Surly the bacteria could have not done its cycle in 4days.
    Could it be possible that the live rock i bought was never alive in the first place?
    Or should i just give it more time.

    I would suggest adding prodibio or special blend to get things started.

    Add a small pinch of fish food to the water to give the bacteria somethign to feed on.

    It is possible that your live rock was well cured and did not have die-off in high enough amounts to spike ammonia or nitrite.

    What is your nitrate reading? If there is nitrate then there was also at some point ammonia and nitrite.

    For me monitorign of nitrate is key in determining when a cycle has ended or when your tank is ready to accept livestock. It will rise and then start falling as the bacteria become active - when it stops falling (less than 10ppm nitrate) you are probably good to go.

    This is a nano and has no means of nitrate filtration. Or has it?

    Yes i think that will be most correct
    As LPS sold me rock from his livestock tank sump
    So i guess the bacteria never died
    Ill feed it and see what happens

    I am not a advocate of adding nutrients to start a cycle. The cycle should begin with the nutrient input necessary for the live stock.

    By adding any old food is just going to spark algae blooms and allow the PO4 to accumulate on the rock.

    Just let it be for another week or two then slooooooly add live stock whilst monitoring ammonia and nitrite.

    I was thinking of adding a small piece of spiering stint
    Then check of the bacteria feeds
    Ill pay attension to water tests

    If you do go the route you are leaning towards. Add a GFO or GFH to at least remove the PO4.

    BTW what are the other water parameters?

    Salinity
    pH
    Ammonia
    Nitrite
    Nitrate
    Phosphate
    KH

    These are my test results i found this morning being day 6 of the cycle.
    Temp -25°c
    Saline- 1.020
    KH- 10°dKH
    No2- 0.3 mg/l
    Ammonia chart measure - 0.1mgs/l
    PH - 8.5

    Looked on a table chart on side of ammonia box and read
    If PH =8.4 @ 25°c then unionised NH3 =12.27

    Is this a spike in ammonia in my cycle or was i supposed to read the ammonia
    from the colour chart as 0.10mgs/L ?

    Im confused with the ammonia readings
    The colour chart gives 0.10 but the table gives 12.27 when checking PH.
    What should PH normally be? And is it high during a cycle?

    I think that i might have understood the instruction wrong.
    It has a formula
    Colour chart sample X %Nh3 (ph vs temp graph )= divided by 100 =
    .
    0.10 x12.27 / 100 = 0.01 mgs/l
    Which is a good reading i guess
