CO2 and water temperature
Gases are more soluble at lower water temperatures, with oxygen being the most commonly cited example of this in planted tank circles. However CO2 should follow this rule as well. If lowering an aquarium's water temperature (by a substantial amount, say 5 degrees Fahrenheit) - what should be done to the CO2 injection rate? Should it be decreased because the CO2 will be more soluble in water, or should it be kept the same because increased dissolved O2 will balance it out?
