    Hi guys I just thought I'd share my new DIY Rock with you.
    I got some shell grid from the west coast.

    The Dry Mix less the salt, Add it at the very last.

    [​IMG]

    Do not get it too wet.

    [​IMG]

    I start with only the base of the bin covered with some sand; Make a couple of small bumps and holes, Get creative.

    [​IMG]

    Now add Mix,

    Then sand then Mix,

    Then sand then Mix,

    Then sand then Mix,

    [​IMG]

    Then sand then Mix, then sand then Mix, You get where I'm going with this nê. Remember to ensure the Mix always stays connected at least 2cm to 3cm, you can go thinner but then it really gets fragile.
    [​IMG]

    See the bin is getting filled up.

    Now this is the "OMG I'm going to die if I don’t see what it looks like" moment. Nevertheless, be patient.
    Wait for about 3 to 5 days to be sure that all the thin parts are dry enough to handle.

    Don’t just flip the bin over, IT WILL BREAK! Slowly take out the sand by hand, vacuum, or air. Take out the master peace.
    This part really sucks. Put it back in the empty bin fill with fresh water add a small power head. Replace the water every so often and repeat for 6 to 8 weeks.

    This rock is about 25+Kg and it cost me about R80 and some time.
    BUT Look at all the shape, you can't buy this in a store!
    PS' Pictures does not do this ROCK any justice!!

    WOW it looks just like live rock!!! Great job:thumbup: I've heard if you put like ice or dry ice in the wet mix and you make the sculpture the ice will melt after time leaving big grooves and holes but this thing looks awesome!

    Very interesting and really incredible shapes you have there. Thank you for sharing.

    Did you use normal cement

    No you need to add some water, coarse salt, blood, sweat, a bit of creativity, space and some curing time. LOL

    It's a fantastic technique, with awsome results.

    One thing to bear in mind though is that apparently crushed shell can have a lot of PO4 in it so test it properly before construction.

    Very lekka result though.:thumbup:

    Thanks, something I forgot to mention is that when you build it in the sand you do it upside-down, the rock needs to be flipped over when you remove it from the sand.

    @Schalkdk as you might gather later on in this discussion i am very anti artificial rock manufacture. I also, 10 or so years ago, thought this was the best thing since bubblegum, a quick buck was to be had, until certain facts were pointed out to me. I stopped the effort.

    I am interested to hear and will try and understand why you embarked on this project.

    Well to be very honest! My main reason behind the Rock is that in almost 17 years of diving I hardly ever saw a rock pile reef except for harbour walls and broken down piers. I could not find a single big piece of LR so had do make my own. I'm only starting with the hobby and I'm sure I still have a LOT to learn, but for now I'm planning to stick to only the most hardy of fish and softies. I live close to the sea so weekly water changes is no problem for me.
    I'm very open to your main dislikes w/r to "Fake rocks" Please share!

    Looks VERY good, Schalk! The only thing that I am really wary of - is the shingle that you have used. This might not be the best idea........ in the long run...

    BTW: I LOVE the 4x4 shovel you are using! SSSSooooo - you do any off-roading lately? ;)

    BTW: out of (my) interest - what do you drive? (what 4x4)?

    IMO, Natural harvested LR is a sustainable source. In other words it regenerates all the time as long as reef life exists and revolves.

    Artificial rock, is made up of cement/calcium deposits that is mined from many years, billions and billions of years, of evolution. So the cement took a few billion years to be created only to be quarried down for a 20 kg piece of LR. WHO is going to replace the wonderful piece of land that the contents of this ALR (artificial live rock) consumed?

    I, and I am sure many reefers will agree, that the reason to be in this hobby is to save, understand, give longevity, protect, the environment and marine world we live in.

    The more we can do to impact less on the non renewable resources of our hobby the better. IMO

    Schalk - the "Shingle" I am referring to, is the "rough" stuff (the black and dark bits)...


    BTW: funny thing ;) I have EXACTLY the same shovel - and EXACTLY the same model 4x4 ..... sorry thing though: mines blew it's oil cooler, later on it's one diesel injector seal - and then broke the (brand new) cambelt....

    So - now - +-R26000 later - I lost ALL interest in mines. So - now - as soon as it is running again - I am getting myself another 4x4....... :(

    mmm what type of materials were use to build your house/office and and and, I think you can only make this type of statement and be true to it if you only house tank bred fish and corals

    I'm sorry if I offend anybody but this renewable resource thing does not make sense to me. Do you stay in a mud hut?? Do yo drive a car?? Do you own anything plastic? Your For that matter do you use ANY of our fossil fuel generated electisity? I'm sure that the worlds reef would take a much bigger hit if everytank owner suddenly took 20kg of LR, compared to our Cement & calcium deposits!
