Bringing this back from the dead since there is a lot of talk about planted tank and discus across multiple threads right now. This thread has very informative info. Do you guys feel anything has changed? or is this info still valid?
Edit: even better, I just learned my apex system does what the milwaukee ph controller does.
You have revived a very informative thread Mando .
Kudos for your search and investigating abilities .
I also tend to belive that 24/7 injection of CO2 with PH controller is the safest way to inject Co2 in a discus tank .
