Good points Cy and these are all things I'm concerned about as well. I'm still planning on trying it out for a few months just to see how it works out. One thing I will do is call them to ask how they deal with the issues that you are bringing attention to before I make my final descision. If it's working for the Seattle Aquarium, then it can't be that bad.
Times are tough and if I can cut my costs and still get great water, it's a win/win situation for me. Also, I live so close that it makes a lot of sense for me. Right now if I do 50 gallons of water changes per month, I send between 150-200 gallons a month right down the drain and the money with it. I'll still need to by some salt to bring it up to 35ppt so I can still help out in contributing to that 12% margin.
