Salmon will prefer pure mountain glacial runoff only. They wonder the whole
system until the water picks up enough metalic salts which prompts them to
return to the tank to breed. When you see them cavorting in the tank, it's
time to service the system. The most difficult aspect of the service
procedure is casting the fly through the tank fill hole to reap the harvest
prior to draining.
