No Wendy, I havn't tried that only because I don't want to go that route. It's such a pain to keep track of that when you start messing with the PH using those PH up or down chemicals. I would rather figure out which stores I have good success with thier bettas with, and stick to them. So far that's the local PetCo.

I don't know about PetSmart because I havn't bought any from them in a long time. They add that blue stuff to thier betta's water and you can't tell what color they are OR what kind of shape they're in...so I don't buy there.
