Zinc

I have about 9 months manganese dosed in an amount 2 ppb/day.
My ICP tests always showed 0 ppb, I tried to increase the dose to 10 ppb/day, as a result in two days of the experiment, the SPS coral hidden their polyps, LPS like Caulastrea and Euphyllia began to lose their heads.
From this I drew two conclusions - the ICP test does not see lower levels of Mn, and level of Mn at 20 ppb is fatal to coral.
When I see here level 960 ppb, I can not imagine that this is possible.
Most likely this is the wrong measurement.
If not, then how they were able to raise so high level of Mn ?
It is a very active element, and it is impossible to keep him in this transcendent level by so scanty additives...
 
the measurement is not wrong, the reading is consistent and confirmed. what you all need to understand is we do not use nsw values as our benchmark, most peer reviewed studies you are reading are conducted for environmental purposes ie: scientists/biologists are removing corals off the reef taking them to a lab and trying to replicate the exact water values they came from, then exposing the corals to a range of environmental factors in an effort to find out why corals are dying on the reefs.
what we do is vastly different we are not interested in nsw, to be honest we find it counter productive, we are simply manipulating xoozanthellae densities and populations both in the coral and the water column, stony corals are extremely resilient and have but one goal [survival at all costs]..,..
 
Have a look at the xooz densities on these acros

That being the case, you would expect that you would be able to replicate the coral death that other scientists have observed (e.g. at copper levels of 0.1 ppm) if you used the conditions of their studies just with your metal measurement protocol. Has such an experiment been done?
 
we are not in the business of intentionally killing corals...

for the record im not trying to prove your studies wrong for all intents and purposes they are accurate.....just not relevant..

The interesting thing is I'm not sure how accurate your testing is or how relevant it is to the household aquarium.

I do think it interesting and very relevant to coral farming. But still question the accuracies. My questions on testing hasn't been answered either.

You don't know that, unless you've tested it. Investigating and explaining discrepancies between your results and the results of others isn't the antagonistic thing I think you're perceiving it as. It's not about proving people wrong per se, it's about figuring out what's going on. With such drastically different results from those that have been come previously, the burden of proof and explanation is going to be quite a bit higher than just, "This is what we do, it's different than what you've seen, and it works well for us, so we wanted to tell you about it."

I still want to hear about it, of course. But then it's more akin to information from a skilled artisan, or an interesting case study in closed-system aquaculture (which is honestly where almost all information in this hobby comes from). Interesting and perhaps valuable, but it's not convincing from a scientific perspective, which is the kind of evidence you seem to be claiming to have.

Which is why I'm looking forward to the paper that comes out of this. Perhaps you have done a great number of experiments that you don't want to talk about prematurely, which is fine. But you seem to continually respond to criticism as though you are being attacked. If you don't want to discuss things until the paper comes out, why not simply say so?

Also tested at the southern cross university.... omg you guys are a hoot seriously...

And I've also ask what they use for testing. I saw ICP in one post and asked what type. Then there's the method/calibration/protocols used as well.


If you want to promote this as scientific research and discovery be very prepared to get asked for details. Especially details that can make a big difference in your results and accuracy.

im getting that info as we speak exact model number will be posted shortly,
also i am not posting this as scientific research, you are the ones saying metals certain metals above certain measurements will kill your corals, im showing you there are exeptions, we are not some two bit operation with a couple of frag tanks in the garage we are a full blown aquaculture facility do you really think we havnt done our due diligence and had these tests confirmed......really?

at the end of the day i dont care if you believe or not, it is what it is and if you cant get your heads around it thats not my fault, tell yourselves whatever you need to justify it..... mabe one day you will be lucky enough to come across some of our frags. im sure youll be happy with them......

peace out....
 
Spslvr, there are others of us here who would love to learn more about your experiments with metal dosing and the mechanisms at play. I hope you don't bow out of the forum because of the rough reception you've received in this thread. I've followed your farm thread from the beginning and was excited to read the additional details you shared in this thread. Please keep it coming!
