I filled out the Pool chart entry form and refreshed the Excel'ish spreadsheet, and it seems to have updated accordingly. Thank you for pointing me to that form.

I've been using 6% unscented Walmart/Target bleach to chlorinate the pool. I also have a floater with a 3 inch Trichloro-s-triazinetrione tablet (Leslies Pool leftover from last year), hoping that will slowly increase my CYA level.

My utility water has a CH of 90.

Thanks!
