I have 2 1/2 ac pond all of my down spouts run in the pond. The pond is about 150 ft from house, so when the softener back washes and that is twice a week.I think about 15gals a flush. I've heard this is not enough brine water to affect the pond. most of the water goes into the ground. But over time some will work its way down there. this has been going on for about 2 months due to fact I had to stop it from going into the septic. In using block salt no chemicals. What do you think

Thanks Dave
