Actually, I never said I was going to monitor ORP on these tanks. Merely test whatever water quality parameters we can to see if any changes in water chemistry can be observed. As I said, the results of the first test will help to guide what we do next and if no effect on ORP is found, then it certainly would not be neccasary to monitor it for subsequent tests.
John_Brandt":12qjmkum said:If you don't cover all your bases, and make assumptions, you set yourself up for being accused of poor experimental design.... This is a common flaw with bona-fide scientific experimentation in the field.
I think you are flawed in your basic assumption that this qualifies as "bona-fide scientific experimentation." I have sufficient investigative skills and scientific knowledge (degree in Astrophysics) to generally state that magnetic devices of this genre are a fraud. I understand the science, I can read their web site, and I can tell you is it B.S. All I am doing with these tests is attempting to remove the complete lack of any control or objectivity in what we have so far: "I bought one and my tank looks great!" It is a well documented phenomena for almost any product where the results are subjective that anyone who spends money will be subconsciously predisposed to see positive effects. I simply want to remove that element.
This is never intended to be held to the same standard as genuine peer review scientific investigation. Even if somehow we were able to do that, do you think it would make a difference to the manufacturer? Or for that matter, to the people who have already bought one? The claims for what this device does, and about how and why it functions already fly in the face of any rational or scientific principle -- I have no illusion that anything I can do will change that.
All I want to do is put some sort of objective analysis in front of those who have not yet made a decision, or who might be interested in the product but possess a healthy skepticism of its claims.
