Yes, my Chlorine levels did get low, but I was checking them each day, sometimes twice. Maybe should have checked thrice. Anyway, I will try to be more vigilant this summer.

I'm hoping Ben's test kit will be a great help since I was relying on pool store numbers for combined chlorine readings.

Thanks for your help.

By the way, after a few weeks of using tri-chlor pucks last summer, I began using bleach, but it was too late. My CYA level had reached 100 or so and at that time I had stumbled on the great poolsolutions site and realized the significance of that high number.

Say a prayer for me as well. That algae nearly drove me nuts last summer. My pool guy wants to continually dump copper-based stuff in there. The first summer I had the pool, I relied on his expertise. He said sanitize with the aforementioned pucks and when the algae came, he went bananas pouring in copper stuff.

I'm keeping my fingers crossed that I'll be able to keep it algae free, thanks to this site.
