We still need to know a few pool details- especially size...
The pH increaser will work, just a lot more expensive than the borax. I would shoot for a pH of 7.5, add however much of the increaser it tells you to dose based on pool size to get there, then just work the chlorine to clear the pool. Don't worry about anything else right now- pH between 7.0 and 7.8, and chlorine- probably 10-15 ppm chlorine until pool is clear, then we can work on the right numbers from there.
