Added 160#s of salt to my 22K IG pool this weekend after reading posts and going back and forth on it. Didn't notice any significant difference or taste but I need to add at least another 20-40#s to reach 1000ppm. I didn't feel dried out after swimming all weekend but I do not know whether that is the salt or just my body getting used to the pool. Dumping and mixing the salt was fun though!!
