Celestial Pearl Danio / Shrimp in CO2

Anyone else using CO2 in their CPD tank? I just setup a new tank. Going from their 5.5g to 17.5g and injecting CO2. Question for those doing CO2, what is the lowest PH we can go without impact? I was running 6.5 before CO2 and now it is 6.0 or 5.9. Seems low, but thought I would ask others with real world experience. Thanks!

I am interested in other peoples thoughts as well.

I am currently running CO2 in my shrimp tank and the population is growing like crazy. I am not chasing a specific ppm of CO2 just 1-2 bps to help the plants.
I have had the thought of adding a small group of fish like neon or cardinal tetra or some CPD.
