First thing is to kill algae. Put two gallons of bleach in the pool and keep the FC to 15 ppm by adding chlorine over the next few days until all of the algae is dead and cleaned up. You will know it is dead when the pool turns cloudy. Vacuum to waste or filter, then clean filter.

At this point you do not need any baking soda or borax since your Alk is high and PH is high. You need acid. I use muriatic acid. You can start with a pint and then re-measure your PH and Alk after you have cleaned up the algae problem and your chlorine has dropped to below 6 ppm.
