I am using the 25ml water level. Today's reading was adding adding 31 drops to get pink water to change to clear for free chlorine. I then aded 5 drops of R0003, then I only had to add 2 drops of R0871 to get the water back clear.
Yes, with your CYA at 55 ppm, you need to bring FC to 20 and keep it there until you're not losing any chlorine overnight. How are you measuring the CC? Your FC+CC=TC, but there's no way to have a CC of 10 unless your pool is a total swamp....

I said that wrong, it was 31 drops using the 10ml...so 31*.5 was the 15.5 and 2*.5 was the 10 on cc....SORRY
I added 2 more gallons of bleach this afternoon and now my readings are:
20 FC
1.0 CC
7.4 PH
110 TA
380 CH
55 CYA

Reading this morning:
FC 11
CC 1
PH 7.2
TA 100
CH 380
No test for CYA, having to order more.
2 * 0.5 = cc of 1, not 10--that makes a lot more sense. Get your chlorine back up to 20 ppm--if you let it continue to yo-yo up and down, it's not going to clear up. Consistency is the key!!
Also, you don't need to continue testing for CYA each time--that number shouldn't change unless you're doing a huge amount of draining/refilling, or using chlorine that contains stabilizer. Save the reagent unless you start using trichlor or dichlor (which I wouldn't, because your CYA will easily get out of control if you do).

Latest numbers:
FC 20
CC .5
PH 7.4
Good. Now, as Janet said above, try and maintain the cl at 20. Test as many times per day as you can and each time (no such thing as doing it too often), add enough bleach to get back to 20. Do this until you can go from sundown one day until sunup the next day without losing more than 1ppm of chlorine.
Ok, have finally got pool to where I am only losing 1 ppm of chlorine. Last night reading was:
Chlorine 19.5 Today: 18.5
CC .5 Today .5
PH 7.2 Today 7.4
TA 90 TA 90
CH 380 CH 380
CYA 38 CYA 38
Pool is still very cloudy.
Ok, you should be just about there. Keep it at shock level for just a couple more days and you should see it starting to clear. Keep the pump running and filtering, backwash as needed, and brush the pool at least daily.
Are you seeing your filter pressure rise? Are you noticing any of the algae coming back into the pool from the return?
