A change in pH of 1.0 equals a change in ppm of CO2 of 10X, not 100X.
I disagree with Amano, partly for the thrill of doing so, but mostly because I think we get the best results if we try for 30 ppm of CO2 in the water during the time the lights are on. Generally, that means the pH will be higher in the morning, after the CO2 has been lost due to our slight surface turbulence. Then, as we add CO2 while the lights are on the pH will drop until we hit the equilibrium point where we are adding as much as we are losing through the water surface.
I'm not quite ready to challenge Amano on the quality of my plant growing skills, nor on my aquascaping skills, nor on my algae control, nor............ |
