From my first test with the TF test kit on 8/22/07 - keep in mind my filter was broken, we'd just moved in to the house, and the previous owner was using trichlor tabs in a floating feeder.
CYA way way over 100
Numbers from 9/25/07 - after new filter, several partial drain & refills ($200+ water bill - OUCH!) & BBB method
The water is clear & sparkling, no chlorine smell.
According to Jason's pool calculator, I have a CSI of .34
When I run the polaris cleaner overnight, I'll often find 1 - 1 1/2 cups of white, grainy material in the bag in the morning. I'm wondering if this could be due to the high CH, or if it's just bits of my pool's finish that are coming off.
The pool is about 20 years old, and there appears to be a piece of rebar showing through the finish in one spot. At first I thought it was just a stain, but I put on a diving mask and went down to have a look. I could see fuzzy tendrils of rust on top that brushed away with my hand and can also feel where the finish is missing.
