Actually, if you're still cleaning the pool you want to shock the water up to 20ppm. You'll have to make do with what you have but it's do-able. I estimate your pool to be 23,100 gallons... It could be 20k, or 25k, but this is good enough. 8 gallons of 6% bleach should bring your FC to around 20 or 21. You can use the CarlD Shot Glass dilution method but you'll need 3 shots of distilled water for 1 shot of pool water to see a chlorine level of 20 (assuming your kit goes to 5).

Or you can look for the OTO test to go deep yellow, but not orange.

Unfortunately, the 8 gallons are the FIRST time. You'll need to test and boost your chlorine back to 20 till your water can sustain it...

Once it's completely clear, then you can go into the maintenance level AnnaK is talking about.
