Donya,

I wouldn't worry so much about your CC level. I do think that with exposure to sunlight that it will reduce over time. As for the PolyQuat 60 addition, I would not add that when you have high chlorine since the chlorine breaks down the PolyQuat 60. The good news is that the broken polymer is still effective against algae (according to the manufacturer that I contacted) but there's not much sense in consuming so much chlorine at this point. If I were you, I would stop keeping the chlorine so high and just let it drop with sunlight. Just keep it above 5 ppm FC to ensure you have enough to finish off the CCs.

Are you adding PolyQuat 60 weekly just as an insurance policy to prevent algae in case your chlorine level gets too low? You shouldn't need to use a weekly algaecide unless chlorine levels drop too far (relative to CYA level). Also, if you have been regularly using Borates to raise your pH, you might consider raising their level to 30-50 ppm since that will also inhibit algae and you won't have to keep adding PolyQuat 60 which isn't cheap. See this thread for more info about the Borates.

The CCs aren't a problem unless you notice a strong smell that prevents you from enjoying your pool. Keep us posted with what happens as sunlight starts to hit the pool.
