The addition of gas CO2 will lower your pH to a certain degree. Usually around 0.5-1.0 pH using DIY CO2 and a good diffusion method like the hagen ladder. I don't think there should be anything to worry about.

If you want to do less frequent waterchanges to bimonthly, you can dose your fertilizers less and at the same time reduce the lighting period to 8 hours.
