    After 12 weeks, I decided to post some pics on what my Nano looks like.

    The tank water parameters are as follows:

    Volume 130L
    PH: 8.2
    Alkalinity 6
    Temp: 26
    Nitrite: 0
    Nitrate: 2 (this has been fluctuating between 0 and 2, depending on water changes)
    Ammonia: below limits of test <0.01
    Phosphate: below limits of test <0.05
    Calcium: 450

    The live rock came with 5 green mushrooms which now have multiplied to 9 and three green brown button ployps which have now multiplied to 5.

    The inhabitants are:

    2 Clown fish
    2 Banggai Cardinals
    1 African Flameback Angelfish
    1 Cleaner shrimp
    1 Turbo snail
    2 Reg legged dwarf hermit crabs

    I have lost one turbo snail which died a day after I bought it and a hermit which molted and got chowed by bristle worms.

    I have been struggling with the odd cyano breakout which comes and goes but it seems to be subsiding.

    I wish to thank everybody here for the excellent advise and for the freindly way in which it is given. :thumbup:

    Hey Kevin,

    Looking really nice there :thumbup:

    Your alkalinity appears to be a bit low . Is it fairly stable at 6 dKH or does it vary ?

    Insofar your cyano outbreaks are concerned : What salt are you using ?
    I also still struggle with cyano outbreaks which come and go. Although I've noticed a pattern emerging. Following a water change I get cyano for a day or two and then it subsides until the next waterchange.

    The alkalinity has gone down slowly, I have added calcium hydroxide (all that did was push the PH up) and sodium bicarbonate (no effect). I will up the amount of water changes (I am planning on doing two 30% water changes two weeks apart).

    The cyano seems to come and go. I have changed from 'Real Ocean' to Tetra. I have noticed that the Tetra salt dissolves completely, while the 'Real Ocean' left some sediment behind. The cyano still appears using the Tetra. I hope is just because the tank is very new and still needs to settle.

    The cyano only seems to grow on the crushed coral substrate and not on the live rock. Maybe there is something in the substrate that enables the cyano to grow????

    The algae blooms have almost gone, but I have noticed that when I add a new fish, they come back for a few days then go again.

    Unfortunately the leather coral in the picture is sulking. Since I bought it (thanks Neil :)) it has doubled in size. When it is finished sulking it will cover that rock it is on completely. In a few months I will probably have to frag it.

    I am still looking for a hammer coral or torch coral, if anybody knows where I can get one, I would appreciate it.

    Kevin,

    Idol Marine in Midrand has quite a few torch corals. Give Adriaan or Bob a call, or go past their shop. Well worth a trip .:thumbup:

    Strange that the Bicarb didn't assist in raising the alkalinity. From my experience the normal Bicarb will raise the Alk slightly , while having a slight lowering effect on the pH.

    Whenever you increase the bioload it is quite possible that you will get a small diatom bloom. IMO , it probably has to do with the increase in bioload. It takes your biological system a few days to catch up with the increased load.These will lessen as the tank matures

    The reason I asked what salt you're using is because I use Real Ocean. After every waterchange I get Cyano. This dissappears over the next two to three days until the next waterchange. But, it could also be due to the fact that the tank is still "new" and hasn't stabilised as yet.

    Lastly , I found that my weekly waterchanges of approx 20-25% keep my calcium , iodine , Mg etc. in check and I have no further need to dose at all.

    Just a thought. ;)

    They change colour, when they contract they turn metallic green and when they expand they seem to turn a pink green colour. The colour depends on where they are placed in the tank, the higher up the pinler they get and the lower down the more metallic green they turn.

    Kevin,

    Looks like Ricordea Yuma . They do have many variations in colour and like you've alreay mentioned it pretty much depends on the light they are under.

    Mine appear green/blue and brown at the bottom of the tank. When moving closer to the top of the tank they appear purple/orange.

    I agree with Apollo that they are Ricordea Yuma's. Love the colour of them! :thumbup:

    My Nano is now getting to six months old.

    The soft corals are growing like mad and even the candy cane has doubled in the amount of heads it has.

    The rics are starting to throw off babies, which I am going to stick to some DIY rock this weekend.

    I may have to get rid of the bigger ones as they are outgrowing the tank :(
