I had thought of demolishing my pool, but city guidelines.....too much money

I tested my pool water 70,000 litres and these are the results
I did add about one box of borax and the numbers came up a little. How do I bring the combined chlorine down?? Do I just add a few bottles of Bleach??


free chlorine 5.3

total chlorine 6.1

Combined Chlorine 0.08
Ph 6.6
Hardness 190 ppm
Alkalinity 50
Cynaric acid 100
