I agree with John that if we have enough, the four salts used by Dr. Ron should be tested first. Also the bag of salt should be desolved in water in a similar way Dr. Ron did. After all it was his bioassay led to this project to verify his data. I definitely believe testing saltwater samples...
I hope we can at least test the four salts Dr. used in his tests. That will hopefully quickly answer the two questions raised which are very valid, does the salt contents change over time, and are we correct that the manufactures' analyses can never be trusted?
Which ever the results however...
Am I curious to know what metal contents are in most the salts? Of course. In fact I am in the process of testing my own salt and tank water.
But is this the best way to spend the money? no. In most researches, one looks for or experiences effects, before searching for causes, because this...
The beauty of a toxicity test is you don't have to draw any conlcusion, it is by itself conclusive if the test is designed well to represent our tank environment.
The problem I had with Dr. Ron's study was it was not a typical tank environment he tested, otherwise his tests would have been very...
Tom, l like what you said, but please realize what you proposed is very different from what was posted by Matt initially. The plan calls for analyses of a long list of metals in every salt we can find. But it is not a toxicity test. And at cost that may go over $13,000, I agree with some...
Alright then now after reread the initial post, I understand the purpose of this test is to provide an independent study of the metal contents in the salts. I am not too sure how this is relevant to the Dr. Ron's study but obviously his study provoked this new effort.
I continue to support...
But what if our test results validate the salt analyses results Dr. Ron used in his article, then what? Nothing will change because those don't believe the study was conclusive will still think so.
If our tests dispute the data used in Dr. Ron's study, then what? His study will still be valid...
Certainly I like to know every metal in every salt known to man, but We'd rather our money used in a more meaningful way: what will be the actual effects of using different salts in our tanks. I also believe that only the salts that are commonly used should be tested first.
I'll donate more if...
Just added $20 to John's donation page.
I want to add my 0.02. While it will be great we learn every bit of trace metals in our salts, there will still be no definitive correlation to the tank mortality rate. Some salts may contain binding agents (intentionally or not) that allow the metals...
