Thanks so much for your response. You guys are the experts.

I have a 30,000 gallon in-ground vinyl liner pool.

Since my last post I have added 3 and 1/2 gallons of bleach and 2 bags of shock. Pool still looks the same (cloudy, but somewhat blue) - here are my new numbers.

Thanks again in advance.
