I didn't Google that, Im going off of what a hanna checker reads fresh mixed blue bucket Redsea salt at, which is supposedly natural sea salt via evaporation.
I'd expect more contaminants from the 'natural' product (the ocean is humanity's biggest dumping ground) but I could be very wrong (depending on grade of synthetics used).Red Sea salt is a very capable mix, but their marketing is misleading. The base of their mix is evaporated seawater, but it's not as if they simply evaporate seawater and shovel it into a bucket. Some elements precipitate as seawater concentrates while drying out. Many of these elements will not separate when rehydrated. Most notable among these are probably calcium and carbonate to form calcium carbonate, but there are likely others.
At the end of the day, Red Sea has to add additional elements to their mix to make up for deficiencies caused by the drying process. It's not pure evaporated seawater. From a "synthetic" vs "natural" standpoint, there's probably not a significant difference between Red Sea and something like Instant Ocean.

Now you have me concerned, and researching a bit more, several sources are stating copper NSW concentration is .09ppm, molar concentration is .0000014
Im assuming you are referring to molar equivalent?
? can you elaborate?
Thanks!
From my understanding there are small traces of copper in a reef system. Small amounts is acceptable and will not hurt your inverts
Im still hoping @Randy Holmes-Farley can elaborate a bit more as Im concerned on the levels of Cu I have tested on established reefs as well as newly mixed SW are far above .0000015 ppm, maybe Im not taking molar equivalent into consideration?
Not saying he is wrong by any means, Im not a chemist, so I hope he can dumb it down so I can understand why a hanna checker is giving me much higher readings than NSW is supposed to be at?
explain it like Im five? lol
I had the same concern when I switched to ESV B-Ionic but HOLY WOW have I been happy with the results. Wouldn't worry about it
The Many Methods for Supplementing Calcium and Alkalinity - REEFEDITION
There is no aspect of reef aquarium chemistry more important than calcium and alkalinity. Many of my previous articles have described various aspects of these systems in detail. In reading those articles, aquarists will note one pervasive theme: that maintaining appropriate levels of each are...www.reefedition.com
...
For example:
You have copper in your aquarium at 4 ppb and salinity of S=35.
You add a two part additive that over the course of a month raises salinity to S=36, and raises copper to 4.02 ppb.
Then you correct the salinity back to S=35 by diluting everything in the tank with fresh water, and you get a final copper concentration of 3.9 ppb.
...
I did an icp test and saw copper in my tank! Then I questioned where it had come from, as I have never added anyWouldn’t it be better to supply and maintain a natural level? You are falsely assuming tanks generally need to lower copper. It is uncommon to see any copper in ICP tests of tank water.
I did an icp test and saw copper in my tank! Then I questioned where it had come from, as I have never added any
Then I asked my LFS for a break down on the salt they used (Tropic Marin Pro) and it had copper as an additive. So that is my concern. I also searched the internet to find any other sources of copper! And found out that some foods that we feed or can possibly feed to our fish and coral have some level of copper in them
After digging more I found that some sources are stating Cu concentration of NSW to be .25 ppb , which would be .00025ppm correct?
so .00025ppm if converted correctly? taking into account the molecular weight of copper? does that equate out to be the the .0000015ppm that you suggested?
However Hanna states the ULR Cu checker HI747 has a range of 0-999ppb with a resolution of 5%
On the HI747, I get ~70-90 ppb on thriving reef aquariums as well as fresh mixed salts
so = .07ppm of Cu?
Is the hanna just plain wrong? why do we as aquarists put so much trust in their instruments then?
I also remember a ICP "review" where someone sent out samples to 3 different companies and got back 3 wildly conflicting results.
What can we actually trust these days?
Im pretty confused
So good reason to keep up on occasional water changes (even with an 'ideal' product)? Thanks for the info, always appreciated!
