Personally I wouldn't give you 2cents for IO but everyone has their preference based on the needs of their tank and what they are willing or able to to for the tank in terms of maintenance. There is no one perfect salt though and each has it's benefits and downfalls.
I just hate to see things made complicated when it does not have to be.
