It's junk.... just kidding. I don't know a thing about it, maybe someone else can tell us GOOD things about it. But I was just curious, do you know why your pH keeps rising? How do you test you pH? If you don't add acid when it gets to 8, will it continue to rise? My pool pH will also rise to 8, but it likes to be there, the pool looks and feels good, so I don"t mess with it much, have had no problems. What is your alk level? If its high, your pH will tend to follow it up.
