I have been setting up a planted tank to house Discus. I know that most people have their CO2 on a timer with their lights and was curious how much their pH fluctuates first thing in the morining when the CO2 was off (should be high) to when the lights are just about to turn off at night (should be low). Is this fluctuation ok for fish like Discus that seem to stress over pH changes?
I currently am running my CO2 with a solenoid connected to pH controller. I have the pH adjusted so that when my CO2 dropchecker appears a yellow green it will turn off/on to keep close to that color. I am using 4kH distilled water in my dropchecker. My biggest fear with my current setup is that O2 will be low during the night when the plants start to take it in since CO2 is constantly being injected/controlled by pH.
Are there any Discus owners out there with some tips. Other forums don't seem to have any Discus owners with injected CO2 setups.
