Thanks for all your help on other issues. What are the consequences of leaving my alk at 240. As I understand it, it will help my pH stay steady but there must be other issues. I'm new to this pool stuff but this site is a great way to learn and all of you are great help and I appreciate all your input.
Thanks,
Dave
