Steve you have to go check out the past 2 issues of Reef Keeping mag, Eric and Kim did a couple articles that outlined the experiment, there's nothing that has been done this well before. I think they did as much as they could to maximize the experiment's data set with the resources they had. I'm really looking forward to seeing the quantitative data.
I just wonder what the result of this is going to be. Doing the study once is going to yield interesting info but I wouldn't say definitive. If you performed the experiment say 10 times or even once with 10 samples of each salt you would have a much better chance of identifying flukes that could have thrown the results way out. I'm looking at the pictures of the IO tank and I can think of a half dozen things that could have spoiled it. I'm sure that the authors will try and make that point but I'm afraid it will be lost. I can just see every post somebody makes with cyano problems being answered with "IO gives you cyano, switch salts" over and over again. Maybe it really does have something out of wack though.
