This may be true, but many other people have not detected any silicates or phosphates yet claim to have had the brown growth. Because of this it seems that there is a good chance that the cause is something completely different that we aren't or can't test for and that's why I'm so skeptical about so many people claiming it's the salt. Tanks get algae blooms and other problems that seemingly appear out of nowhere for no reason, even well kept tanks sometimes, and since we don't really know what this brown growth is or what's causing it I just don't think it's as simple as putting 2 and 2 together.
What is so strange about the notion that there might be inconsistencies between batches?

flaunt said:Well, I have a little bit more anecdotal evidence concerning Oceanic salt and whether it's any good. I read about the original test that mojodeli did, so although I didn't consider it "proof," I thought there was a chance my Oceanic salt could do the same thing. So last night I mixed up a gallon and let it sit in the sunlight all day today. I just got home and looked at it, and the first thing I noticed was that the water had a brownish tinge to it. I know I'm not imagining things, because I had a gallon of plain water to compare it to. I don't see anything growing on the sides of the jug I used, but it's only been 24 hours. I'm going to let it sit another couple days in the light to see how much worse it gets. I need to get another brand of salt and try the same thing so I can be sure it's actually the salt, though, so while I'm not ready to draw a conclusion I am concerned.
