Hi Marie -

Thanks for your thoughts.

Pool is colored plaster.

I switch between cal hypo and liquid chlorine for shocking. So, I'll stop using the cal hypo and monitor calcium.

As to the chlorine level, it's been discouraging to get it much higher, as the water seems to 'get green' as it rises. [Weird, I know.] Well, I'll try it again and also get my ph a bit lower.

Someone asked me the other day if I had any hobbies. I said, "Are you kidding? I have a pool!"

Thanks again,
Paul
