Yes, but as Janet says, just adding polyquat should bring chlorine levels down. I find when I shock my pool up to (say) 15ppm and then add a quart of PolyQuat, 48 hours later my FC is near zero.

Here's what I would do: Add two quarts of polyquat and get some test cheap strips or an OTO kit. Test the water every day until the strip shows FC of 10 or slightly less. Or use the OTO kit and dilute the pool water with distilled water 4:1 (4 distilled to 1 pool). When the OTO reads "5" that means TC is close to 25ppm and you can measure with your 2006 kit.
