I'm curious about the salty taste we have in our pool water. We do not have a SWG. A few years after the pool was built, we noticed that the water had started to taste just a little salty, and in the 4th year it started to get more noticeable. We drained and replaced a lot of the water, and the taste was gone. Now it's a few years later, and last Summer the taste was back and I'm sure it will be more noticeable this Summer. My question: Would this be due to the fact that I use liquid chlorine almost exclusively for sanitizing the pool? I know there's sodium in liquid chlorine, so I've been assuming that this is what's causing it. But on the other hand, I don't think I've ever heard anyone else make this complaint/observation about using liquid chlorine, so I'm wondering if there might be another issue that I'm not aware of that's causing this.
If it is the liquid chlorine, I know that there's the cal-hypo form of chlorine available, but our water is very hard so I didn't want to be adding more calcium to the water.
