    Hi all,

    I just want to know if lava rock could be used as a cheaper substitute for other rock in a reef tank. The lava rock will be used in conjuction with normal live rock. @CW

    Thanx

    Thanx for the reply flappy, wil the silicates have a direct effect on the fish, coral, or both?

    I'm only starting my tank up at the moment, so no live stock yet, and it will cycle for a while... will the silica release deminish over time or not?

    There are no rules around the possible release of silicates..It could happen over time or not at all but not worth the risk in my opinion..best to use a calcium carbonate based product...This is what liverock is made from...

    Hi there @louisva and @flappy

    Well ive also done some googleing on this lava rock.
    Yes theres a few different kinds of lava rock.

    But this one weve got hear is used in fish farms and so on.
    What they do is they brake the rock into lots of small peaces and then use it in filtration.

    So why would it be bad in a marine tank.

    Yes i know if it releases silicates (spelling hehe) it can be bad for coral and fish.
    But why do the fish farms use it?
    And why is most ppl still useing reggies play sand for there tanks?

    Ive used reggies in 2 of my 4 tanks that ive had and no problems.
    My brothers beed using it in both his tanks also.

    So ja. i dont see the problem in it.

    And in my opinion to be able to have the proper result in whats right and whats wrong you will need 3 identical setups.

    Setup No1:
    Regies, lava rock and the rest of the standard thins we need in a marine tank like heaters, power heads, sump, lights and we all know the rest.

    Setup No2:
    Regies, dead rock (the proper marine live rock with nothing living on it) and the rest standard things.

    Setup no3:
    Regies, live rock and the rest of the standard things.

    Then all 3 setups will have to run for 30 days.
    Then you have to add exsactly the same amounts of fish, coral and inverts into each tank and monitor them for 1year.

    I think that will be the only way of determining the best result posiable.
    Obviousely 10 years will be a better time frame.

    And obviously every specimen added must be the same kind and size.

    But still my opinion is lets give it a go.
    Ja i know, most ppl will say were irisponsiable to do so.
    But then i ask you, what if we create an environment for fish and coral to populate and grow?

    Thanx seank

    Nice read

    Ok so what im rhinking now is to give it a go and see what the tests say.
    Its up to @louisva still to decide if he wants to try it.

    Ill take my test kits there and to the testing when we start the tank.
    In the middle of the cycle and also at the end.

    Then also every month so we can see if theres a quik increase of phos so some levels going hay wire.

    Thanx for the input ppl

    So true there.
    Still no definite answer there.
    But its like that all over the net.

    The best to do is just to test constantly anyway

    Very, very bad, and they only grwe on my lava rock. And before the Gurus take me on, this is not to say that it does not grow elsewhere, but in this specific tank, it only infested the Lava rock.

    Eish, it looks like you had a lot of "bad" in your tank then. What is it called, is it some kind of algae or a plant or fungus??? and what is the effect on the other live stock?

    Guys bottom line is when a Newbie comes onto the forums asking for advice they want good solid advice based on tried and tested methodologies that work....no one wants to be experiment let alone pay for the privilege...

    Too be honest I have used it before with no ill effect
    I know people who have used it with terrible results and others like me who have used it with no problem at all.
    Don't forget that the rock is not specifically made for marine tanks it is often a waste product out of furnaces, etc.
    So at the end of the day the choice is up to the individual if they want to take the risk or not but IMO I wouldn't do it, when I used it I knew little about it and it turns out I was lucky enough to get a 'good' batch cause I have heard more bad then good results from people using it

    Wow thats alot of aptasia.
    Ive had it before and nuked some in my new tank cos i used some of my old rock that was in my sump but not as bad as that seank.

    Thanx for all
    So true flappy.
    But noobs also dont have unlimited budgets like some LFS think.
    So they have to do what they can to survive and to have a marine hobby.

    And by meaning noob ill include myself.
    Cos i just beleive ill always stay a noob, cos every day i learn something new.

    Ive also made mistakes in this hobby so i wont let my brother in law do the same.
    Ill help every where i can.

    Wel im gona help @louisva to try this and see if it works.
    He can get some free coral from me and my brothers systems and if all goes well he can decide if he wants to carry on with the hobby.

    But thanx again for all the input ppl.:m106::m106:
    But now its time for a :peroni: or:peroni::peroni:hehe

    Thanx flappy, I actually enjoy the whole controvercy surrounding the topic, but what you are saying is very true. I like to see everyones inputs but what i would like more is to, at the end of it all, be able to choose the correct, or just the most correct oppinion...:m106:

    I Appreciate the input Reefhead, I really dont want to be one of the guys with the bad batch at the end of the day.
