    Good day and Hello To All

    I have just started to setup my 1st Marine tank and must commend everyone on this forum for the information they share and willingness to assist people.

    Some info on my tank.
    Bought 2nd hand and will one day build my own one,
    LXBXH 1.8X60X60
    it has sump area each side
    I am very big in to the DIY thing so I am busy building the sump and Skimmer (skimmer has worked well but just want to upgrade to a needle wheel to make the bubbles a bit finer).

    Sump will be 80X50X40
    Inlet and outlet chambers either side 10cm wide which leaves 60X50 for DSB.
    water will be pumped from inlet chamber to skimmer, for skimmer to algae scrubber box, then from algae scrubber box to BDS.


    Current I have my tank busy cycling and not going through the sump.
    I was lucky enough to get live rock that was fully cured (bought it at exotic Boksburg, some guys tank had bust after a few months so it was a good buy) my ammonia leaves went down to 0 within a week and a half and nitrites down to 0 a week later. I have added a Maroon clown and a two yellow tail damsels (one damsel died within a hour). They are doing and eating well. live rock has lots of little white feather worms on them and they always seem to be out and I have two small pink rock anemones. (that’s what I have been told they are)
    I have about 20kg of live rock with about 25kg of Volcanic rock. I have used crushed coral as the base (volcanic rock and crushed coral came with tank.)
    Question: is the volcanic rock ok and is the crushed coral ok or should I replace it with play sand?

    I am getting my upgraded lights today (currently T8 globes) 4 T5 with hood. 2 12000k white and 2 20000k blue.

    Welcome to MASA!!

    Just a quick one from me: You might wanna think about changing your subtrate in your display tank. It is a bit to course. You will battle with Nitrite issues later on.. .;)

    There is the everlasting debate about the buffering qualities, aragonite, Crushed coral ad infinitum - personally I think without having an acidic water, the calcium carbonate will not break down fast enough to make a difference

    Thats why we add CO2 gas to a Carx, to make the water acidic enough to break down the calcium carbonate.

    On another note, I went with crushed coral, which is cheaper than aragonite and I am very pleased! I went for the 0.5mm-1mm CC, about 1/3 the price of aragonite, but 4xmore than reggies (which is also cool)

    Reggies play sand will work perfectly. I've seen and heard many reefers use playsand with no issues at all.

    I'm still a ferm believer in aragonite which is very expensive, but in my opinion worth it. But like mnd123 mentioned, this is an ever lasting debate.

    A very WARM WELCOME to MASA Nick. I see you live in the hood that I grew up in ;)

    Nice size tank, 1.8 metre.....

    I agree with the substrate. You would in the long term be much happier with sugar fine sand.....

    Yes - a lot of people prefer aragonite. But, there is absolutely no scientific proof that crushed coral or aragonite will sufficiently buffer your tank's water. You would STILL have to add alkalinity buffer later on.

    What is the "vulcanic rock" exactly? What does it look like? We have a resident geologist on MASA (Neil_H) as a member. He would be the best person to give you a professional answer on the rock.

    But, as far as my (read experience) experience goes - you get TUFA rock (which is white and very light) which is being sold as "volcanic rock", and you get the stuff that is sold for gas fireplaces (which is dark red/brown/black in color).

    The prior is good to use in marine tanks, and have not proven to leach anything bad into our tanks....

    The latter, is very bad to use - as it can leach many different unknown metallic substances into our tanks, causing tank "crashes", life loss, etc....
