Zinc

From what I gather the palintest9100 is just an entry level deuterium-tungsten UV-Vis spectrophotometer. So by itself it can't really measure any metal concentration, at least not at the low levels we are talking abiut. They would need colorimetric reagents to measure anything. So it's accuracy would depend more on the accuracy of the reagents and experimenter, in addition to the intrinsic accuracy of the spec. Unless I'm missing something.

I'm willing to share the main metals which are iron maganese zinc and copper thses level are on
Iron 0.34 ppm
Maganess 0.98 ppm
Zinc 0.45 ppm
Copper 0.35ppm
We make up a solution with 1lt
Mn is 245mg
Zinc is 89mg
Copper is 67mg
Iron 2grams
Then we dos 40ml x 2 per 11000lts

Are you sure that these figures are correct?
You dosing Mn-1,78ppb/day and you have level at 980 ppb ? (NSW=0,4 ppb)
Zn-0,6 ppb/day, level - 450 ppb ? (NSW=5ppb)
Cu-0,48 ppb/day, Level - 350 ppb ? (NSW=0,9ppb)

We are not wanting to keep it at NSW
It is usless in a closed system or a normal sps reef tank because no one runs nitrates and phosphate as low as the reefs .
A reef tank has which runs higher NP need higher trace elements ... study will be done by February will post up then .
Plaintest works for the levels we need

Yes I am sure in a closed system the trace elements need to be a lot higher
I will post up all my results of the trace metals test
I will only put up zinc iron maganese and copper

It is very strange, I have approximately the same dosage Mn,Zn,Fe, but the level is kept 1000 times less.

Your corals do not have a chance to survive in such conditions,
I hope no one has reiterated your experience yet.
 
Thanks for the input. I'm very interested in reading the results but honestly highly skeptical of the methods and accuracy.
 
A little bit late to the party. Been dosing zinc for about 10 months. Specially to help with SPS color and growth. I feel there is more than enough papers that show how important zinc is to SPS.

I am currently dosing 0.0016 ppm of Zn daily.

At the moment we are doing a paper on trace metals should be finished in February with Southern Cross University the paper contents will be trace element uptake growth and colour.
What i have notice is when different trace metals are added Alk and Calcium would drop
Alk would drop from 135ppm to 115ppm over a 12 hours and calcium would also but only 30 to 40ppm per day in saying this we have about 6000 frags in each system which is 11000 lts each all under natural sunlight
I'm willing to share the main metals which are iron maganese zinc and copper thses level are on

I can post up photos of photos tomorrow of growth or look on our facebook site or have a read of the fram forum

Are you dosing 40ml per day or 80ml per day. At 40ml you are adding 0.16ppm per day at 80ml you are adding 0.32ppm of zinc. correct?

I agree there's also more then enough to show Fe and Cu are important too.

Absolutely. But I don't add those. I found that limited Fe doesn't seem to affect tissue growth the way that Zn, Mn, and Cu can. I dose Mn as well but have been cautious of adding Cu due to the bad rap it has always had. I do know a few people who have recently started adding Cu and they have not had problems so I may start to play with it in 6 months or so.

Anyone dosing things like RedSea's color part C is dosing Cu, Zn, etc.

I thing the papers you mentioned , wrote for the importance of fe/Zn and fe/Cu. Why do you focus just on Zn and mn , and not their analogy with fe?

I never thought such high concentrations of trace elements, can instead of being harmful , being beneficial, in conjunction with elevated nutrients. Very interesting results, waiting more information from your paper.
 
Because strong biomass growth happened with even the lowest amounts of Fe in their tests. But not so with low Cu and Zn. Deficiencies of either Cu or Zn resulted in poor growth for S. kawagutii in the study. Also found was with low Zn/Cu was elevated Mn and Fe quotas.

So for me, I took that to mean keep Zn and Mn in the water column for absorption and you are setting up the right conditions for good growth.

We have played with Fe and Mn in higher levels works well for growth not so much colour

Now we are experimenting with
Nikel
Colbats
Chromium
To add in the mix above in the other posts i think they are important to growth and colour and health of the corals

smh

With out seeing the paper, that I hope is peer reviewed, I don't know all the variables and skeptical they are all known as well. Especially considering the lack of accurately testing those trace elements and any contaminants they may bring with them.

Then there's also the fact how does this apply to xyz's tank. And if it will fry someone else's SPS, LPS, mushrooms, leathers, etc. And so so many other questions about many different known and unknown variables.

A lot more testing would need to be done.

Just showing a picture doesn't mean a whole lot.

There's a lot to be skeptical about right now.

I still would not suggest anyone dose anything other then food and saltmix if you do water changes.

Even JBNY that is dosing isn't going near those higher levels of dosing.
 
We are not talking about the average hobbiests tanks, obviously there would be alot of adaptation required.....
