    I've got some ex-live rock/coral skeletons lying around that I'd like to clean up and use for base rock. I'm concerned about it leaching nasties back into my water. Is there something I can do to make sure it's clean? Maybe a good soaking in bleach and then RO?

    Just boil them for 20 minutes.

    I've seen guys use very diluted pool acid or vinegar and then boil...

    thats risky, bleach will soak into the rock and may leach into your system,

    just give them a good scrub down with a hard brisstle or wire brush,soak in saltwater for a week with a pump, and if you want, add some bacteria to it and give it a quick cycle

    I'm a bit skeptical to use acid or anything similar on anything i will eventually put in my tank. Even if its low concentrations. If any life survives at 100 Degrees C after boiling they deserve to be in your tank ;)

    I used bleach, with no problem... even when I revive my purigen I use bleach... the important part is to use Seachem prime afterwards, the prime will sort out the bleach with no side effects....

    Main concern is phosphates leaching. Bleach degrades pretty quickly, not really worried about that.

    I have just taken some liverock covered in algae, boiled it for about 3 hours and its now in the sun to dry. After a week I will chuck them in the toilet tanks so that any life that died (bristleworms etc inside the rock) can leach out whatever they want. Will leave it in the toilets tanks for about a month and then dry again for future use.

    With R1000's in livestock I think rather safe than sorry is a good approach.

    How about throw them into your pool for a week let everything die then put in sun to dry.
    Then a week in WC water

    Yup, that was the post I saw... Muriatic=HCl

    The acid is quickly reacted with the organics in the rock, along with the CaCO3... So it ends up slightly lighter and more porous.

    Cool, thanks chaps. The HCl method seems the best way to go.

    It's gonna be going into my seagrass/macroalgae tank, so I don't mind a small amount of phosphates. As long as it's not a huge amount I'll be happy.

    In the early days of this hobby we would remove al the dead coral and rock and bleach it every couple of weeks. My reef with those rocks are still running and that was 1971.
    Just use "regular" bleach, no scents. Then soak it in fresh water and let it air dry. Bleach is chlorine gas and it will evaporate and leave nothing in the rock. I did it 873 times, give or take a few. :biggrin:

    I soaked my rock in normal water with some bleach for two weeks, geez did that water stink!!! Then I just put it to cycle in a tub with a heater, skimmer and little power head. I added a drop of zeobak and then I just vodka dose once a week. Its been two months and no3 and po4 are around 5

    Place them in a tank with salt water and flow pumps. Use LaCl to extract the PO4 from the rock. it will bind to the PO4 leaching from the rock. This might take about 4 weeks. Keep adding LaCl every days. When done. Rinse the rocks with RO/clean salt water.
