Bromine Chemistry Question

Results:
Home: No difference in TA after agitation. TA still 220-230 depending on how dark a pink-red I go for.
In-The-Swim: TA 240 and he went dark like my 230
Leslie's: First he used his reagents. TA 110, then mine TA 150. He stops when color is greyish.
So, I will trust my reagents and just be frustrated that there has been no change in TA after 2 full cycles of MA.

I think I may have figured out my problem, however. Even though I read the directions over and over.... I goofed and am feeling pretty embarrassed.
Your instructions say:
4.) Begin aerating.
5.) Test your pH AND your alkalinity. Continue adding acid to MAINTAIN your low pH until your alkalinity reaches your target value. Once it does, continue aerating, but allow the pH to rise to the normal level.
I have been getting my pH down to 7.0 and then aerating to bring it back up to 7.5/7.6 and then lowering it back to 7.0 and aerating back up to 7.5/7.6. I see that your instructions say MAINTAIN low pH. I am now going to keep it around 7.0. I will reduce the amount of aeration at least until I know the MA has completely circulated.
Does that make sense? In the meantime, should I continue with 1C dichlor every night or switch to the calcium hypochlorite?
