Whats your thoughts, am I on the right track??? Can I keep adding borax in small amounts to get to the right level?

Your alkalinity is low as is your pH, so you could attack both at once by adding Soda Ash (Sodium Carbonate) or you can add both Borax and Baking Soda (bicarbonate of soda). Probably the safer and easier thing to do is to keep adding Borax to get your pH to the right level first and then add Baking Soda (bicarbonate of soda) to bring up your alkalinity (TA) to at least 80, then follow this with a final touch-up of Muriatic Acid (if needed, since the Baking Soda slightly increases pH) to get to your desired pH (7.4?). Or you can go back and forth between your Borax and Baking Soda (only start adding Baking Soda after you get to a reasonable pH of at least 7.2) to try to get to your levels without any overshoot -- it's no big deal if you do and need to correct it, it's just a matter of taste.

You show no calcium hardness (CH) at all. Do you have a vinyl pool or a plaster/gunite with grout pool? If you have a vinyl pool with no tiling that has grout, then you won't need the calcium, but if you have a plaster... pool, then you will.

I'm sorry I don't have the borax calculations in my spreadsheet yet, otherwise I could tell you how much to add. So, keep with the incremental changes and note how much affect each change makes as a guideline.

Good luck. You are on the right track!
