It's safe to have a water softener on a septic system, correct?
I don't have a softener system currently, but I figure that these things dump LOTS more salt in the septic than the comparatively small amount of reef salt I consume/discard in my septic monthly..
Though, I have two full residential septic systems w/ leach fields connected to my home, as I purchased and tore-down my neighbor’s house (was too close to my house, a dump, etc) then connected the septic systems in parallel.
IME, I have seen no ill effect dumping my 30-44 gallons of saltwater in my septic tank(s) monthly.
