Going to drain my 22 ft. pool and do a better job of setting it up next year, support frame does not look good as it should. Question is, will the salt water kill the lawn, maybe to the point that grass will not grow back, I don't know? I can siphon it 100 ft, but it still would be on the grass. I think I have 300 or more lbs of salt in it, that seems like it will do some harm. Thanks
