That's what I understood. However when I get my PH down to 7.2, it's back up to over 8 within a week. Perhaps that's just part of the BBB method, and I should just be happy to acid each week to knock it back down?

I have the same trouble you do with Fill water....it will always creep up when you have to replace from evaporation.....although slowly.
Mine seems to shoot up as fast as the PH does.

My plan is to get the TA down to somthing reasonable so that I can get a stable PH....then forget about the TA and Stop aerating.
Mine too, but it's not working very well

Remeber that aerating will raise your PH. If you have a PH you like, then Stop aerating and dont worry too much about the Alkalinity.
When I do this, the PH continues to shoot up. It's hard to stop aerating when cannon balls are so much fun That's why I started this thread. It seems like just swimming and general splashing around is causing the PH to climb. Since the alk climbs with it, I figured I'm not doing a good enough job aerating, and the carbon dioxide formed from lowering the PH is being re-converted to whatever instead of gassing off, giving me the increased alkalinity reading.

Unless you have a problem with scaling I would forget about trying to "fix" the TA because your fill water will mean a constant battle....you'll never get it to stick at a low number.
My grand vision was to get the alk down, then as I have to add an inch or two of fill water, I can easily beat it back down. Do you think this is futile?

No matter what you do you'll probably always have to add Acid....the good news is that your PH should stay fairly steady compared to other pools. The High TA doesnt cause the PH to shoot up....thats another problem and may be related to your TA increasing on you.
If my PH would remain stable, I wouldn't give the alk a second thought. Whats the other problem you mention in your last sentence?

Thats my understanding from the technical explanations yes...but I have seen it bounce around a bit, I always attributed it to my testing or other factors.
I've tried to be as precise and consistent as possible in my testing, but it's possible I'm getting bad readings, I guess.

Thanks a bunch for the input
