I'm about to install my Milwaukee C02 setup, but am concerned about PH swings at water change time.

My tap water is PH 7.2, I need to get to PH 7.0 for the recommended CO2 level (per thekrib).

Is this a concern with 25% weekly water changes? How about with larger water changes? I generally put the hose right into the tank with chlorine neutralizer dropped in near the hose output.

That wont be a problem even doing a 50% water change.
As a matter of fact I wouldnt even worry much of moving a fish ( not all but most ) from 7.0 - 7.2 or vice versa directly. It would be even more suttle a change through delution with the existing tank water.

Dont worry about a 50% water change. On your tank the change in pH from 7.2-7.0 will be negligible....Remember in the wild where these fish grow there are HUGE pH changes...Rain showers! Your fish should be fine.
