Do I have to worry?

I think I might do a DIY CO2 thing for my plants. You know, with the 2 liter bottle? Now, do I have to worry about pH drops? If so, how do I control this. BTW how many bubbles per second?

At night, run an airstone. That will help to stabilize your pH.

at night run a airstone, since plants dont photosynthesize at night.

i bought the nutrafin CO2 kit for $25 and it pumped a bubble every 2-3 seconds

What I meant was a nutrafin anyway. So I can just put an airstone on a timer at night and there I go?

yep, thats basically it
