I've been using white vinegar instead of other acids (trying to stay organic as much as possible) ...... it lowers the PH, but the next day it's right back up to over 8.0 and without any water changes ......... when I do water changes, I put vinegar in the water as well as ascorbic acid, the PH is 7.4, but the next day ...... you guessed it, over 8.0
