Sounds like a lot of bleach to me. I'm in SoCal, where are you? I do think you'll be happier with the BBB method of water treatment.

At a CYA of 30, I have to add a fair amount of chlorine, but not that much. I tend to keep it more around 40, especially during summer. Still, when it is really hot more is required.

I fight pH too. I have a waterfall (not always on), a spa spillover and a little fountain bubbler. All that aeration drives up the pH. But I find it pays to maintain it anyway. It certainly helps the chlorine be a more effective sanitizer.

Well, you'll get better advice than this, but that's my experience.
