Don't worry about the watergram slide in the test kit. It isn't very helpful and is confusing. Just use the chemistry advice given on the forum instead.

Since you have a CC reading of 1, you need to keep your chlorine at shock level for a bit longer. With little to no CYA yet, your shock level would be around 10 - 12ppm. You want to stay at shock level until:

1) You can go from sundown one evening to within one hour of sunrise the next day without losing more than 1ppm of chlorine
2) You have a CC reading no greater than 0.5
3) Your water is clear

At that point, we recommend keeping the pool at shock level for one more day for added insurance, and then you can let the chlorine level drift down. Take a look at the Best Guess Chlorine Chart in my signature above for needed chlorine levels (which are based on your CYA level).

Run your pump 24/7 while you are trying to clear the water and clean your filter as needed.

Dichlor is acidic and will drop your pH as you saw. You want to make sure to keep pH between 7.0-7.8. To raise pH without raising alk, you can use 20 Mule Team Borax (laundry aisle at Walmart). Add a cup or two to start with and see what that does to your pH. Add it slowly to the skimmer while the pump is running, breaking up any clumps. Wait a few hours, retest and then redose if needed.

Hope this helps!
