Saltwater Tank and Septic System

[sphelps]

I always pumped salt water from changes onto my lawn, in one small spot too as I never got around to getting a longer hose or connecting to the sprinklers. That section of lawn to this day is still the healthiest so I never saw any negative effects from the salt content. I probably averaged around 50gal a month from my 300 gallon system over around 2+ years. Often had large dumps of water in the 200 gal+ range as well from the numerous circumstances requiring such large water changes. I think it's ultimately still a small amount of salt given the rain and snow we receive each year, would highly doubt long term effects are really possible but I would suggest spreading it around to be safe rather than a single location.
