    Ok, so I don't know much about water params during cycling so pls tell me if this is OK.
    My tank's been cycling for 3wks now, I have tested 3 times so far and:
    No amonia,
    nitrite only on 3d testing (week 3, last night) very low,
    nitrates from the beginning and this spiked in week 3 (last night) jumped from about 2 to 8.
    ph at 8.3
    sg at 1.025
    temp running at 25 - 26.5
    alk sitting at 3 but i don't know the units - seachem test kit.

    DSB was seeded after 2 days, LR added after 5 days (only 4kg but a lot of live on it), dead prawn added at 8 days, and some more DSB seeding at 2.5 weeks from other source than first time seeding.

    DSB has lot of pimples on surface and starting to see some 'root' things going down the glass, saw a few 'pockets' forming low down in the sand against the glass last night.

    Amphepod (i think - looks like fleas) numbers on LR has grown
    and some of them running around on the base rock.

    Diatoms on sand and in corners of DT and sump tanks.
    some very light green colouring on base rock, nothing on LR.

    Have a small, about 5mm, snail like think crawling on the glass and sand,
    have something hiding behind the rocks, only pokes around the rock when it's dark and hides away when I shine a torch on it, very difficult to see, tooks like a bundle of brown cat hair.

    Does this sound ok?

    These graphs should help illustrate how a cycle works

    Give your tank a few more weeks - do you plan on adding more live rock?

    That cat hair thing (lol) might be a hairy gorilla crab. Put a glass against the live rock or burry it in the sand if deep enough. Put a small piece of fish or prawn meat in the glass. He will climb in and cannot get out. Rather do it now during the cycle as he might cause havoc with sensitive inverts/corals in the future.

    thx,
    @viper well the graphs make me worry even more cause it doesnt seem my tank is doing that....
    @tobes, The plan is to let the tank be until end of March and then review all parameters and decide to start stocking or cycle longer.
    Yes I'm planning on more LR, currently have about 20kg base rock and 4kg LR, want to add another 6kg LR end of feb and then check how full my tank is, i'm aiming at about 30kg rock in the DT, later on I might remove some base rock to the sump and add more LR in the DT.

    I googled pics of the crab you said and not sure if that is it but i will try the glass-trap and see, will probably move some of the rock when adding the 6kg of LR next weekend and hope to catch the 'CREATURE' then :)

    Always a good thing to add more good quality LR :)

    It's even better that you are so patient with the cycle - I wish more guys are like that :whistling:
    My previous tank was started on the 1st of Jan, I put my first fish the end of April - because I added some rock inbetween and wanted to make sure there were no ammonia spikes.
    My next tank will be up soon :slayer: - live rock cycling from November last year already :)

    good luck catching the creature :48:
