Now there's the balancing act, isn't it. I don't use CO2, because I'm just
not that motivated for the plants' sake. The plants are in there for the
fish. IF you keep GH VERY low, like under 1º, then you can push KH up a
little. Or better, keep GH and KH at arond 2º and use a hydroxide like NaOH
rather than a carbonate to raise pH, and then use the CO2 to bring the pH
back down to the 6.0-6.5 range for the fish. You need to be careful with
NaOH because it is very reactive when being wetted. Mix it with the water
first. Some "ice melters" are NaOH. I'm sure it can also be found AS NaOH
on the web somewhere or at a local chemical supply house.
