I dont have any immediate plans for CO2
injection, but have a question in the interest of learning something new today.
causes a pH drop. I just read on another thread that 1.0 to 1.2 drop is desirable. How does this affect fish? Are you limited to selecting fish that are low pH tolerant? If you decide to use CO2
on an already set up and stocked aquarium will the pH drop kill the fish?
