KCOTA seems to be saying that there is a conflict between the KHA program and what was posted by JR and REC (through Koi cop)? Truth be known, I don't see a conflict at all.

Seems you have compiled a formadable list clarifying the issue koicop. Considering the Koi Health Advisor Program, in the Water Quality Section continues to promote the use of salt along with the principle text for KHAs “Advanced Koi Care; For Veterinarians and Professional Koi Keepers” I hope you get all this to Spike Cover for his attention.
Excerpt:
“Common salt, sodium chloride, NaCl, has been termed “The KOI Wonder Drug”.A misnomer perhaps, but salt is a proven staple in the health care and maintenance of Koi worldwide…
The addition of one to two pounds of salt per hundred gallons of water (1.25-2.5 ppt) is recommended for most ponds, especially in the Spring and Fall. This is a fairly conservative dosage, but unless one has an accurate measurement method, higher concentrations should be avoided. If nitrite is present, two pounds of salt per hundred gallons is appropriate to reduce the nitrite toxicity. After the initial application, the dosage applies ONLY to the amount of water being taken out and replaced, NOT to the amount of water in the entire pond, and NOT to water being added to replace that lost by evaporation. Except for very short-term medicinal baths at concentrations often around 25 ppt (1 pound per 5 gallons), and administered under tightly controlled conditions, it is not recommended that Koi be subjected to a salinity exceeding 5 ppt (4 pounds per hundred gallons), especially for extended periods.” http://www.akca.org/kht/H2oQual.pdf |

Let's break this down, shall we?
The first thing that needs to be understood is "conversions". 1.25-2.25 ppt tranlates to .125% - .225%. Didn't Koicop's references say .1-.2%? Now keep in mind, if I am not mistaken, the common salinity meters are farely accurate but still have a +/- accuracy of .04%. So, the .025% differences cited are really a non-factor.
Second, Dr. Nick St. Erne in his book, Advanced Koi Keeping also says: "especially in spring and fall". Actually for the same reasons that Koicop's references state, to off set nitites during times when filters may be less than necessary due to water temps being such that the biofilm is not at peak efficiencies to handle possible higher nitrites.
As for "Aeromonous alley?" The key there isn't salt. Having an environment with low cfu counts and low to non exisitent parasites virtually eliminates this "exposure." In other words, reasonable stocking levels in a clean, well maintained pond/filter system.
