After installing a new pressurized CO2 set up for the first time, as expected, the pH in my new tank dropped about a full point. I know this is a function of the CO2 dissolving in the water. I have attached a picture of my 2 tank's pH test results. My question I guess is two-part:

1. Should I just live with it at this level or add some pH increaser to balance it out? (I assume it will drop back down at some point and fluctuation is probably even worse for the fish)
2. How do I get the fish from my old tank acclimated to this change in pH without shocking them to death?

Thanks
