I read a mind blowing article in the latest FAMA about trace elements. This guy claims that in 'most common' salt mixes that there is over 100x normal levels of metals such as cadmium, lead, etc.. !! Levels that are near toxic to begin with and that accumulate with time as they accrue higher than corals can sequester them. He believes that there is a connection between this and sterility in fish and 'old tank syndrome!!' If this guy is right, what the hell is this about!! > > ??? Why the hell are levels of metals this high?? ??? (I have to find out what salt mixes he did the tests on. I will post when I find out.) Oh, and he said we shouldn't dose with supplements !!
