    Yes. Maintain your pH. When it rises to 7.8, lower pH to 7.2, then pH will rise again with aeration. Repeat until your TA is 50-60 ppm. Remember that dichlor is also acidic, so each time you add dichlor, this will also lower your pH, but only a small amount. Near 0.2 pH units per 8 grams in your tub volume.
