You've said you like the idea of a high PH pool based on what you've read at poolsolutions.com I'm guessing.
One of the drawbacks of high PH is "increase scaling if your calcium and alkalinity are too high."

In your case your alkalinity is too high and you are guessing (probably correctly) that your calcium is too high, both of which are a bad thing if you plan to run a high PH pool.

I would suggest that you drop your PH for now to prevent scaling, and work on lowering your TA and calcium. Once those are in check, you could then attempt a high PH pool.
