Opinions on Salt

[Phil Slaton]

I have been seeing more and published on the benefits of adding salt to grow tanks. I raise Koi, Trout and Catfish. What is the opinion out there in our Aquaculture world, should salt be added to the tank water in low quantities, say 1 to 1.25 ppt simply to condition the water before fish are added?

Thanks for taking the time to reply
