Long-term salt buildup?

[Charles Gillen]

For the last two years I've changed out my 10-gal tank weekly, using 2
gallons of dechlorinated tap water to which I've added a measuring teaspoon
(seems smaller than a table teaspoon) of aquarium salt and then aged for a
week.

The salt seems to have warded off common fish diseases and my few goldfish
have thrived... but I wonder if I risk a long-term buildup of salt? The 2
gallons I change weekly is far less than the loss to evaporation.

Checking my chemistry today I find ammonia, nitrates and nitrites are
virtually zero, while PH is in the 7.6 range suitable for goldfish.

I'd be more worried about getting salt resistant parasites/diseases.
I never use salt on my fish unless they are ill.
