Taking people or companies at their word is fine if they are reputable, Kent, in my humble opinion has proven themselves as reputable.... If you take the Pope at his word does that also mean Saddam Hussein has to be taken at his word too? Of course not, form opinions, and trust your judgment.
I understand what Gazza is saying I'm not knocking Gazza's opinions but I am trying to clarify that the S-15 report is bogus. Other reports may be more accurate, but when the Scientists at Kent tell me that their salt has near NSW of copper and they also say "I see no reason you can't quote our answers to you" I tend to think they have nothing to hide.
Salts are alot of personal taste, and not so much science for the most part. We support what we like, and we tend to oppose what we don't like, sometimes we like things for nothing more than the pretty package other times we like things for what we consider more concrete reasons. I like what I like because I like it, you may not like it but thats okay. Personally my ability to do trace element testing is limited. I test for Ca, pH and Alk, and soon for Mg.... I Like consistancy, if I have to add 5ml of SeaChem Reef complete 2 times a week, I'm fine with that, as long as my Ca level doesn't bounce around from water change to water change. I like to know ahead of time what I am dealing with, I hate suprises unless they are to my benefit.. which they rarely are, so I stick with what is consistant.
Copper levels 50 times that of NSW?.... dunno, my inverts don't seem to mind, and I don't use a water conditioner that binds heavy metals. FWIW, we tend to run our tanks for optimizing growth and health of our corals, if maintaining NSW conditions were our prime goal we wouldn't be feeding our corals DTs, we wouldn't be skimming, and we wouldn't be adding suppliments on a regular basis. We (speaking for myself anyway) want to see our corals thrive, and grow fast, it's a pat on our own back when we can see a purple cap Monti grow almost closed into a tube from a half tube shape just over a month ago. It is a pride thing, an ego. I like to keep my tank nutrient rich so my corals have the maximum exposure to food. If I thought my salt had a copper content that high I may as well just give up because I would be poisoning my tank deliberatly.
I am looking forward to seeing what comes of this study/experiment Emily linked to.. sounds interesting.
