Added a 2nd DIY CO2 bottle and PH went from 7.6 to 6.6

I added a 2nd DIY CO2 bottle for my 20gal and PH went from 7.6 to 6.6. I'm not sure what I should do, I'm running the air pump right now. The fish are not at the top gasping for air, but I'm concerned about the PH drop.

Is this a planted tank?
A pH drop of 1 point would indicate a consintration of about 30 ppm of co2, which is just right for a tank with plants.

Putting on the air pump makes the 2nd DIY co2 useless as this gasses off the co2 you paid to put in there.

The fish will adapt to the pH differance and the co2 will help your plants.

Yes its planted, I was concerned it was too much co2 or the PH drop was harmful. Thanks for your help.
