I would add that you should do NOTHING to allow your Total Alk to rise or your water can go cloudy due to the high CH.
The tabs will drop your pH, but if it's 7.2 or better that's fine.
IF pH goes lower, I strongly suggest you raise pH either with Borax or via the aeration method--fountains, kids splashing, bublers, etc, but do NOT use any pool store pH chem as it will raise T/A. If you find pH isn't stable we can address that then (remember: It WILL go down using up the wet tablets Ben talked about. That's normal. Once you are only using bleach/liquid chlorine pH shouldn't vary much).
