    I'm currently busy with another little endeavour, and need some base rock/dead rock for that. I was wondering if marbelite would be a suitable cement to use for making base rock, as it should be a lot more inert that normal white cement, creating a rock that does not leech rubbish into your tank and is cured quicker.

    I have marbelite in various colors, so no blue stones... lol

    Any opinions?

    I think the lack of porousness might be detrimental, as it greatly reduces the volume of bacteria that could have bred there... but there are others much more knowledgeable than me around. :p

    I've seen some guys put noodles into their mix to leave small cavities in the diy rock.

    Thanks all for the replies, salt will of course be added, as well as some sand like pool filter sand or the like to get some volume in. Will keep you posted.

    Cheers

    Just wash it off with some vinegar or HCl then leave in RO water for a while. Otherwise the rock is way to caustic to put in a tank immediately... Yes maggie 2 minute noodles, pasta and rock salt make nice porous rock!

    Yes marbalite is fine. The mix is 1 part cement, 2 parts crushed coral, 3 parts mixed coarse salt and noodles. To make it stronger instead of 3 parts at the end you can make it 2 parts, your descretion.:)

    You can place the rocks in RO water and change the water regularly, after 2 weeks check pH of water in container to see if the rocks affects the pH or not... I do it for 3 to 4 weeks before I place the rocks/frag plugs in my tank

    wouldn't waste your time with RO, stick it in the toilet reservior at home, so every time you flush it gets fresh water, test PH after soaking it in like bowl of water, compary a test sample of the same water added in a seprate tea cup or whatever container you've got, if ph doesn't rise with the rock sample then start with the RO, trust me this takes months, My rocks been sitting in a bowl of water for close on a month now, PH still differs from test water, lime leaching, you'll just waste a tonne of RO imo.

    I've tried varios mixes this seems to work the best for me:

    2 Parts Cement
    3 Parts Crush Coral
    2 Parts Pool Salt

    I'm using white portland cement.

    My toilet bowl is not big enough for the piece i have in mind. I have a extra drum,where my ro-waste goes,and it gets emptied every week,maybe i could dump the rock in there and just let it be for a few weeks,then say after 4weeks,place it in the fishpond. Will that work?
