    What has the smallest impact on our environment?

    1) using live rock in our tanks.

    2) using dry live rock.

    3) using synthetic rock made from calcium carbonate.

    4) using synthetic rock made from ceramic.

    5) using rock made from fiberglass.

    Important things to consider are

    A) is the rock naturally replenished from its source?

    B) is the rock made from a material source that will never be replaced?

    C) what other sources of energy are used in mining synthetic materials used in making synthetic rock?

    Lets have a clean debate and thoughts on the carbon footprint.

    Using secondhand old liverock

    Well, that do come with its own issues like phosphates, aiptasia, algae and what not. But no impact on the environment due to my purchase. :tt2:

    Lets look at the calcium carbonate source and what impact it has on our planet. Question how this calcium carbonate will be replaced. Is it sustainable?

    Where the pics of what liverock harvesting has done to the reefs?

    Look at the walls of your house...isn't the cement made from calcium?

    Corals will rebuild reefs and continue to do so. Man will continue to mine and disfigure the environment with a promise to put right.

    Just because buildings are made of cement and mortar does not mean that the method is justified. The material is not sustainable, is it?

    Anyway we talk about our reef tanks and carbon footprint on the reefs and land sources. Just because one source is greater than another does not give free license to abuse.

    What needs to be considered is which source is renewable.

    The question should be is live rock really needed or is it an out dated means of filtration.

    I understand the need for sustainability, but the rate at which liverock regenerates is far slower than the rate we harvest. We do need to think about the mining of calcium carbonate, how much actually gets used in reefs compared to the paint used for building. Without doing the maths, how much less calcium would we use if all our houses were facebrick or if we decreased the size of one or two rooms in our house?

    If we looking at going green and being sustainable we cannot only factor in our tanks, one really needs to change our entire lifestyle.

    Look at it this way.
    If one ton of live rock was harvested from the ocean it will be replaced.
    If one ton of calcium carbonate was harvested from a quarry it will never be replaced.

    I do understand where you coming from, hopefully it will make get people thinking.
    Considering the rate at which our reefs are disappearing, if liverock harvesting really sustainable.
    Where is the carbonate being mined? How much environmental impact is it having on that area? Seeing as is it being mined for other things is the impact our tanks have really that large in the greater scheme of things.

    To add to the debate - what are your views on other media like seachem matrix? It has a massive surface area and could/should reduce the amount of liverock needed

    I think one has to consider the amount of liverock and calcium carbonate there is and the rate each is being used and the impact of this.
    While we wait for liverock to regrow after we harvest, the creatures who use it as habitat die out....are they renewable?
    I agree with David,the Calcium Carbonate used to make artificial rock for our aquariums is not even a fraction of a percentage of the other uses for Calcium Carbonate however the amount of liverock taken that has led to reef desecration has already necessitated the ban on liverock from certain parts of the world like the Kingdom of Tonga.Other countries have already placed huge restrictions on their exports.The other less controlled parts of the worlds where liverock is harvested has led to reef destruction and spin off damage to the creatures that use the reef as habitat.This for me is more serious than the minute carbon footprint that calcium carbonate might have when used for aquarium rock......Our cars emissions and lifestyle has far greater carbon footprint...

    David IMO all synthetic products have a impact. Be it using fossil oils to power machinery to harvest or transport. Or to produce power to process via a kiln or other method.

    yes but this is not a perfect world, we use fossil fuels to make alternative energy products...

    well is mining rock sustainable, yes i think so, as we take rock out the ocean, lava/magma rise and create new rock, we are in a closed system on planet earth so i would think that things will be in balance.
    we might put things out of balance but mother nature knows how to rectify.

    that link is on advance aquarist site, email them

    Dallas get a 503 error on the link.

    In a closed system that we are in ,as you say. Does that mean that the green house gases, ozone layer, CO2 increase will all fix itself and regenerate. We have nothing to be concerned about?

    the site error is there issue, i cant fix it....

    yes if we lived to see maybe 200 years plus, i can only speculate

    Being Eco conscious is good, just need to keep things in perspective.
    This debts can expanded to energy consumption, use of plastics is pumps, etc etc.

    If liverock harvesting is a problem, why not keep a smaller tank? Can the joy gained out of a massive tank really justify its carbon footprint?
