DIY CO2 Injection
I have already leart that DIY CO2 injection can be made from 2L soda
bottles and that the mix should be 2 cups of sugar, 1 tsp of baking
soda and 1 tsp of yeast. I understand the bottle should be filled
almost to the top with watter then. Besides the composition of the mix,
does the temperature matter much? I have some of my tanks in
a rather cold room - the tanks have heater though. And, is it possible
to kill the fish by injecting too much CO2 - either by making the
carbon dioxide replace oxygen in watter of by making the Ph drop too
much? If so, how can I controll how much CO2 is injected with this
setup? Finally, I understand the CO2 will make the Ph drop. Should I
counter this by adding some baking soda to the tank watter?
