    How suitable is Tufa rock for the reef aquarium?

    I have done scaping with it, bu someone told me they may flake and even give off heavy metals.

    This is contradictory to everything I have read on the use of Tufa rock.

    What is the general opinion on the use of this type of rock?

    I'd rather use base rock or liverock personally

    Tufa makes one of the best base rocks. Make sure it is Tufa ie calcium based and not sintered glass. ie volcanic rock which may leach undesirables.

    Thanks Sunburst. I was worried there for a bit. Yes I'm sure it is Tufa rock. Now I don't have to dismantle my whole scape :)

    Hi LappiesReef - just to echo Sunburst's comments. I believe that many reefkeepers use tufa rock as base rock. Without many problems, as far as I know.

    Oh yeah. The Tufa is in my 4FT L shaped tank. I am taking slow with the big one. Student budget... I did the rock work like that for nice corals to go on.
    I also have a 3FT L shaped sump where I thinkthe DSB and live rock can go :)

    As soon as I figure out how to post pics there will be lots...

    Hey Guys,
    What does tufa rock look like? I ahve got a box full of this black/gray rock that is quite sharp to the touch and breaks easily.I bought it from an LFS here in Durban. It looks like molten ash or glass,is it similar. Hey lappiesreef can you post a picture of your tufa rock.
    Cheers

    Hi Shan - the rock that you have seems to be lava rock - the bad kind... the kind that can possibly leach metals and other stuff into the water. Sorry man. Perhaps you can start a thread and post a picture or 10?

    Tufa rock (I think) is more of a blunt-edged type rock. Without really sharp edges - and I think it is more of a grey-ish coloration.

    Will do SHane

    Tufa is white to ivory. Mine feels hard to the touch.

    If i'm not mistaken Tufa is calerous rock formed around hot springs. I think it is mainly Mg and Ca or calcite.

    All books I read reccommneds it for its buffering capacity and look.

    I think the only reason it could not be popular is that ,ive rock is so much better...

    For me though, since I want to add the live rock to the sump and corals to the Tufa it's good for me.

    The ones I bought is also nice and holy. Almost looks like ancieant dinosour bones...

    Going to look awesome Lappies! Just one thing... You probably would have done it in any case, but you should let the sump sit on something flat like chipboard cut to size and shape. Just to be safe. ;)


    Maybe they are! ;)

    Should I put something under there?

    It is resting on polystyrene over the metal.

    As I'm sure you've guessed, I'm not very technical...

    I'll get a pic tonight of my Tufa and how I put them together.

    SHane if you want to see the Tufa, I am starting a thread for my 4 ft and will post them there a bit later. I'll call it 4FT L shape under member systems. I want to post my whole progress there on this one. Like a little diary :p

    Hi LappiesReef - I would definitely suggest putting perhaps some "shutter board" (you can get this from Builders Warehouse - they cost +-R199 for a sheet of +-2.1m x 1.5m
    You can get the people at builders to cut it to size for both your tanks....
    The weight/pressure on the glass might just be too much if you don't have more support directly underneath the tanks...

    Thanks J

    I will definately do it. Now I just need a few stong men to pick-up the tank to put it underneath... It doesn't have water...but the rocks are in in.

    oh and my student budget must recover first after buying Leoash's Nano ;)
