Man.....I guess you haven't done enough reading, but all the goodies that are consumed by are tank inhabitants are replaced when we do water changes by the ingredients in the salt mix......alot of people might dose strontium, iodine, and such chemicals, but the bad thing about it is they don't even test, so you don't really know what your levels are or what your adding......
Yes synthetic salts do have more or higher amounts than NSW, but again it should be pointed out that you should do alittle more research such as ReefCentral in the Reef Chemistry Forum by Randy Holmes Farley and he has a good article there about the chemical composition difference between NSW and synthetic salt mixes.....
I don't mean to be mean or smart, but you'v missed the whole point about were these elements come from.....they definitely don't come from that magic potion bottle you have sitting under the tank.....If you want to go without water changes; by all means do, but your points would be again mundane....maybe you should check out some really awesome tanks and see their regimens!!!!!! I doubt anywhere you'll see in there long term success you'll see them omitting water changes..........
Actually in a very well balanced system, with proper water changes you can almost negate adding a bunch of those extra additives that people think are a must have.........What is it that your corals and such are consuming Ruaround that you just pour from a bottle?
