you may be asking the impossible. every batch is going to turn out different for everybody. some people use tap water, some ro, some ro/di. some people need to change their filters. some salt mixes are not evenly mixed up in the bucket. the chances that 2 people that use the same salt and have perfectly matching parameters is going to be pretty low. there are numerous reports that a lot of salt mixes have wiped out tanks because the mix has been off so badly. you should really test your own w/c water and adjust accordingly or change salt mixes. even the salt studies out there have wildly differing measurements of the same salt brands. the salt issue will never go away. it is trial and error at best.
