CO2 level in planted tank
I have a 75 g planted tank, set up for about a month, fishes are happy, plants are ok, with a minor algae issue. I'm using DIY CO2 with 2X 2L bottles and a DIY reactor. My pH is 6.2 and Kh is 3. Depending on which chart you use, my CO2 level is between 40 to 70 ppm. That apeared too high and I did see fishes come to the top during light off period. Should I stop the CO2 or try to increase the pH?
I use Turface with a little Aquasoil and a large piece of drift wood, they turned my tap water from pH=8.2 to 6.2. How do you increase pH without using buffer solutions?
