    Hi Guys,

    I need some advice on my tank's cycling.

    Background of Tank:

    Boyu 550 - 130 litres
    Stock Skimmer, Lights and Pump
    Removed all Filter media that came with the tank.
    Overflow chamber I put in black filter sponge for filtration and 10 BioBalls I took from Sam's Aquarium's sump filters
    Second Chamber is the Skimmer
    Third chamber is extra 1200 l/h pump for the chiller
    Return chamber is the heater ( never on ) and the stock return pump

    Added about 2cm of Live Sand ( fine white ) at the bottom of the tank
    Added 10 KG FIJI Live Rock
    Fitted extra powerhead inside the tank flowing water over the live rock
    Added 50ml of NitroBac

    Stats as meassured tonight : Tank has been running 7 days now

    Ammonia : 0
    Nitrite : 1 ppm
    Nitrate : 40 ppm ( Might even be 50 )
    PH : 8.0
    Salidity : Perfect
    Temperature : 25 C

    My question is that I have not seen any Ammonia at all in the tank. Tonight is the first night I am picking up any Nitrite reading. Nitrate seems to be stable at 40-50 ppm.

    Since yesterday I am also seeing rust brown growth on the live rock which I suppose is Diatoms ( I actually read a lot on the site... )

    Can anyone please advise me if I am on the right track and maybe why I havent been seeing Ammonia whilst Nitrite and Nitrate has been climbing.

    Thanks in Advance

    Pierre

    tank should run for a couple of days with no movement in Ammonia reading. To ensure that there is no second or 3rd cycle.

    If you can see any life forms on the rock at night, then you can feed a small amount of flakes for them. Really just a pinch. No point in starving them, having them die and then becoming part of the cycle.

    What do you use to measure the spesific gravity with and what is it?

    A few things:

    1.) You need to feed the tank. the best way is to drop a small piece of fish or shrimp into the tank and let it rot for 2 - 3 days.
    2.) 7 days is waaaaaay to soon.
    3.) Microbactor will work "kinda" but it's not good enough to build up a robust bacteria colony, so when you start putting in your 1st fish you'll see another ammonia spike. Best way is fish or shrimp.

    New Meassurements

    I did a water check tonight again, as follows:

    By the way I use one of those old school glass hydrometers to meassure the salidity. I turn all the pumps off and meassure the still water.

    I also did have a piece of rotting shrimp in the water for about 3 days, but still couldn't get ammonia to spike.

    Ammonia: 0
    Nitrite : 0 ppm
    Nitrate : 20 ppm
    Temp : 24.6 C
    PH : 8.0

    Thanks for all the replies thus far.

    Cheerio

    What test kit are you using for ammonia? Is it still within the expiry date?

    BTW, it is salinity, and it is 35g/l which means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts

    1.025 is the specific gravity, not salinity ;)

    New Stats

    Tested again tonight and bought some new test kits as well:



    Temperature 25.3
    Specific Gravity 1.025
    Ammonia 0.000
    Nitrite 0.000
    Nitrate 5.000
    Phosphates 0.055
    PH 8.000
    Alkalinity 2.730meq/l
    Carbonate Hardness 7.700dkh

    Salifert Test Kits used for Ammonia, Nitrite, Nitrate and PH - All Brand New

    Seachem Test Kits used for Ammonia ( to Double Check ), Phosphates, PH and Carbonate Hardness / Alkalinity - All Brand New

    I also found a stray porcelain crab ( busy rotting ) in the live rock.

    My skimmer also started working today, and cleared out some foul brown water and bubbles from it tonight.

    Diatoms are taking over now and growing everywhere, including the rock, sand and glass. Also small signs of green hair algae on the tips of the live rock.

    Just to recap, I have 10kg of Fiji Live Rock in the DT. Tank has been running now for 11 days.

    Any advice guys.

    Thanks in advance.

    Lol, i normally just fill the tank with live rock and salt water and not look at again for 6 weeks. Constantly checking it will drive you crazy dude :) and leave the skimmer off, it's not going to do you any favours

    Nice going...

    From the pictures, it looks as if the scaping is "wall to wall" ? If that is the case, you might have some difficulty cleaning the glass on the sides (inside - with either blade or magnet). For me, that is HIGHLY annoying not to be able to see through the sides! But then again, if your tank is placed as such that it is only viewable from the front, I guess it would not matter.

    As for the scaping, nice!

    Nice going.

    I see some tracs of algae starting on the top rocks. And you got a big turbo snail. I doubt if the tank would have enough food for suh a big vegatarian snail. Especially in the first week. Keep an eye out for him and do not clean the back pane. Leave somewhere for food to grow for him. Else when he dies then you will get your ammonia spike.

    See you also got a chiller hooked up.
