how long can cardinal tetras survive while i change the pH?

i've already put them in and am in the process of lowering the pH to about 6.7 or 6.8. is this low enough and can they survive the slow acclimation?

    You are more likely to kill them by messing with the pH.

    'pH down' is diluted battery acid, and your water has a high pH bacause it contains natural Lime. Sure you can get the pH to read 'correct' by balancing the amount of lime and acid in the water, but that doesn't actually make your water better for the fish. The hardness is the same, and the total dissolved solids is increased.

    Better to let them acclimitise to the water that you have, or change the source of the water you are using.
