marine salts

Good points Fred, it is a shame so many people see the S-15 report and take it as a salt bible, frankly I see it as propaganda. I have had good luck with IO and Kent, I use the Kent because I like the extra calcium/strontium/magnesium. I had horrible luck with Bio Sea and Marine Environment, but thats just me being picky. Now I've been through 3 bags and a bucket of Kent salt, I can add 4 cups to my 10 gallon tank and I get a consistant pH, Alk, and Ca level, thats pretty much all I want in a salt, consistancy and adequate levels of buffer and calcium.

As far as the heavy metals goes, I wonder if using a water conditioner in your tank that binds heavy metals so they can be removed with carbon works to lower the heavy metals. I am not sure if they actually remove them or just bind them so test kits can't read them.
