    Ok some of you have asked me to start a thread on my DIY base rock.

    Here goes.

    Ingredients:

    Portland White Cement
    Kulu Agrit from Idwala. It is a white limestone mined in Port Shepstone it is fine will also work well for DSB...

    To start, get your self a lets say a 1l tub and one big storage containers like a
    Rollerboxes.

    Put some of the Kulu Agrit in the Big SC and wet it not to wet just so it holds its shape for molding.

    Now get a container to make your mix.
    Add 4 Kulu Agrit to 1 white cement.
    Then full your 1l container with water, add the water in slowly you don't want it too wet must be a dry sort of mix. The best thing to do would be to play with till you get is right.

    Mix very well I use my hand with GLOVES

    Now hand drip your mix into your mold container do not pack it or you will not get nice holes in the rock. once you have finished you rock do not cover with the Kulu or it will close up the holes too. leave for 2 to 3 days then move to curing tank.

    It will take about a month to cure and you will have to change the water every 2 days.
    Only strat testing the PH on the 3rd week if it is still in the 10 to 13 ph range dont even bother testing for at least another week. Moving water work better...

    Once the rock has reached the 8.4 to 8 ph range it is reef safe.....

    Happy DIY rocking.....

    Don't you add rock salt to help make it more porous?

    Please test before throwing into your aquarium
    There is and other technique I am working on and it does work well.....

    Same as above but add polystyrene to the mix...

    I have been playing with 1 white cement 4 Kulu Agrit 2 polystyrene balls and a few big chunks...

    The only thing is to dissolve the polystyrene out of the rock you need to use thinners and that mean your rock has to be cleaned well....

    So how I did it was once the rock has been left to dry in the mold for 3 days I removed it from the mold then placed them in a black bag, wetting them and then wrapping them up to keep the moisture in the bag and leaving them for a further 3 days to ensure they are nice and strong.

    Then I took a tub fulled with thinners and soaked the poly rock for 5 minutes each.
    The rocks look really good.

    I then rinsed under running water for a few minutes and cured then on there own for a month with extra water changes and after the first water change the smell was gone.

    I have not tested this technique as of yet...
    But as I said the rocks look very cool...
    Please test before throwing into your aquarium

    Oh And please never ever cure your rocks in your tank!!!!!!
    And I don't just mean in your running tank... I mean even if you have not set your tank up and want to use it to cure you will regret it BIG TIME!!! I did and you don't want to know about it, just trust me it a bad idea!!!!
