Just means your chlorine is higher than 15 ppm -- assuming you are using the 10 ml sample size (the lowest sample size).

OK, I'm a doofus. I went to the pool store today to talk about the differences in their/my cya readings and the clerk pointed out to me that the scale on the sample tube was inverted. Soooo this means they were correct and my cya is over 400. The dot disappears about a third of the way up to 100. Given the logarithmic type scale I can only imagine it is actually over 400.
I'm going to bite the bullet and drain the pool. It was drained once before to have it re-plastered and didn't float so I'm hoping I can do it again. Any precautions?? I've found a way to use the pool pump to drain it. Anything I should be aware of before I start? Thanks kevin

Just make SURE the ground is NOT wet; pools literally float up out of saturated ground.
That's probably not an issue in San Diego, but still . . .
(Embarrassment: it could be worse. I've still never published the story of how I turned a 300,000 pool DARK purple while it was full of swimmers -- testing a new idea that turned out to be a really, really bad one! It's been years, but still is uncomfortable to recall!)

It's too long a story. Ask me in July . . . if traffic dies down.
(I can't believe the metrics I'm seeing today. If it goes up in June, we are going to be SO hammered!!)
