I understand fully what you are saying.
I guess in my febele little mind, I'm questioning why the research that they do is not affected in the same way your tank is. maybe it's the type of research they are doing is why they don't have an adverse affect on their test. Who know? I'm not the one doing the research so I can't answer that.
Maybe at the colder temps of our local water, the excess/unwanted elements do not have the same impact as they do at higher/tropical reef temps. Who knows?
As with all things that I've learned over the last 18 years of having a reef tank and enjoying this hobby, what works great for one person, dosen't always have the same results for another person. Why this is so, I have no idea.
I do know, and have collabrated this with Paul B who is going on 40+ years with his reef tank, that things in our tanks go in cycles. Once you have an estabilished system for I'd say more than 5 years, you start to see the cycles. pauls seen it as well as myself. For him though, he's been in the hobby long enough to see the same cycle several times with more than 5 years between the cycle. Just some more info to throw into the mix. Could it be that the problem your having is actually one of these "cycles" that our tanks seem to go through over time? Who knows.
