lduncan Posted June 17, 2005 Report Share Posted June 17, 2005 I agree with SteveA. I'm sticking with calcium, alk and Mg additives, leave the rest to waterchanges. Layton Quote Link to comment Share on other sites More sharing options...
SteveA Posted June 17, 2005 Report Share Posted June 17, 2005 I suppose I do get a lot of trace element addition from water changes, since I now use salt mix after deciding I was getting too much nutrient from the NSW of Wellington's south coast. No idea what my parameters are as I haven't tested in well over 6 months. I tend to let the corals tell me if they need something.

RnB Posted June 17, 2005 Report Share Posted June 17, 2005 thats what eric bournman says..... stick with the basics.... only minimal additives and only if you can test the resultant concentrations.... the shops hate it, the basics are cheap cheerfull and proven, the snakeoil is Miraculous, Unproven, and EXPENSIVE I have a much better feel for what zeovit is doing now, and feel that there are other ways to achive the same result..... each to their own, zeovit seems a proven way to lower phosphate and amonia byproducts...

reef Posted June 17, 2005 Report Share Posted June 17, 2005 Who really cares if it is not 100% the same stuff or more expensive. Zeolite is Zeolite. providing it can be used in seawater ,some might have more iron minerals etc or more pure etc. How would you like it if i compared salifert test kits to say hagen test kits ? Or deltec to red sea ? You can compare them, The princapal is the same but Red Sea skimmer might work better than Deltec for example. So Zeovit works the same as Tunze Zeolite or better because you are adding bactaria and feeding it. all very simple. At the end of the day the Tank of the Month is based on skill not the fact that it uses zeovit to reduce nutrients. zeovit seems a proven way to lower phosphate and amonia byproducts. I doubt it is a proven method yet as many hobbyist including myself did not get a reduction in nitrates and PO4. It seems to work differently on each tank Quote Link to comment Share on other sites More sharing options...
RnB Posted June 17, 2005 Report Share Posted June 17, 2005 true reef... its not scientifically proven, and there are def not published metrics documenting the rate of removal and capacity of the zeo.... or the exact process that is taking place, tho it seem pretty clear to me now that elevated iron levels pretty much show what and why things are happening. the zeo should be way cheaper as well, its used by the tonne in waste processing..... its ok if you have a 100L tank, but i now have 600L and the next tank will have over 2000L in the sump/display...... it will be.. once we find a source, just like subbing in food grade calcium hydroxide instead of BRAND X Kalc.... I can buy 25KG of kalc for $80 then i meet an electroplater guy who says so what, i can get that bag for about $40 8) sea water is basic stuff, all the trace elements are cheap and cheerfull I bet the zeo is sold to these guys for next to nothing.... its the pet trade game... abit like the party pills that cost $0.20c to make and sell to punters for $10 or more each! each to his/her own drug of choice.

reef Posted June 17, 2005 Report Share Posted June 17, 2005 Has anyone actually measured the iron levels before and during the zeovit system?? Cant be that hard to do. Quote Link to comment Share on other sites More sharing options...
lduncan Posted June 17, 2005 Report Share Posted June 17, 2005 It has been done. http://www.teichratgeber.de/ma_zeovit.html Element Symbol After 5 days After 47 Days Iron .......... Fe ........ 12300 ........... 7930 4370mg of iron gone in less than 50 days from 1 kg of zeolite. That is a LOT of iron. Layton Quote Link to comment Share on other sites More sharing options...
reef Posted June 17, 2005 Report Share Posted June 17, 2005 I see that, it is a old test as zeovit do use a different zeolite, Be good to test the tank water. Quote Link to comment Share on other sites More sharing options...
lduncan Posted June 17, 2005 Report Share Posted June 17, 2005 To give you an idea of how much iron is leaching. Typical surface concentrations in the ocean are around 0.000006 ppm. If all of the above iron which leached from the zeolites was dissolved and accumulated (which it wouldn't, but lets say it was), it would correspond to 4ppm! Testing the water is not simple at all. Similar problems to testing phosphate and iodine. The various speciations, iron (II), iron(III), organically bound iron complexes, make a simple test impossible. It's easier, and more accurate, to test the zeolite before and after. Layton Quote Link to comment Share on other sites More sharing options...
