If it's the right kind of salt, up to a point salt is beneficial even for freshwater fish. Again, I'm 6 ppt, and seawater is something like 35 ppt. My soils and groundwater are all rich with salt. Nearby my farm are "Saline" county, the "Salt" Valley, etc. My big pond has finally been getting adequate rains so the salinity is back down to less than 1 ppt, so it will be interesting to see if I grow FA this year. I'm currently setting up a plan to buy a couple of waterfall pumps so I can eliminate use of well water altogether. If it rains normally that won't be difficult at all. Well water is expensive, so it would be nice to stop using ground water. My current annual average usage is less than 2 gallons per minute.
