Water testing and left over trichlo

[JimK]

With a CYA of 120, (assume you diluted), I would aim higher with that FC. See: http://poolsolutions.com/gd/best-gue...e-chart.html#a

+1

You need to maintain "shock" level appropriate for your CYA level until all 3 of these conditions are met:

1. Water is clear
2. CC is less than .5ppm
3. Overnight FC loss is less than 1ppm (test FC after sunset, then again the next morning before the sun hits the pool)
