Question CO2 levels and time to get there
Question regarding CO2 levels. Previously I was using an inline diffuser but switched to a cerges this week. My question is on when my tank should be reaching 30+ppm of saturation. My co2 comes on 1 hour prior to lights, but I see with my pH probe that it takes probably half the photo period to reach a full point drop on pH. Should my water reach that level sooner or is this ok and how the tank should be fed the co2? I've had some green spot and fuzz algae issues so I am curious if I've been doing it wrong this whole time and should be feeding more co2 so it reaches this level sooner.
As an additional question, what is the average pressure you all run on a cerges?
