Vacation Strategy

[KurtV]

With a cya of 30, I certainly would not shock it up to 30. That would not be too good for your liner. I would probably shock it up to about 10 and then have somebody throw in some bleach every few days like Carl said.

If I'm reading it right, this chart from chemgeek says that 30 ppm FC with 30 ppm CYA is equivalent to about 3 ppm with no CYA. If that's the case, I would guess that 30 ppm FC would not hurt the liner.
