Thanks for the link. I have a chlorination canister that is not used that has two small tubes linked to the plumbing. I can connect a small air pump to the return line tube and get a nice flume of bubbles out of the water inlets to bring to total alkalinity down.

I am one week in on the "Jacks Solution #2" process, I'll let it Run one more week and then bring the pool back into balance.

Any specific pH target I should aim for in this effort?
