Now that the CO2 system is in place I'm keeping an eye on the drop checker. I took a wild guess and initially set the bubbles per second to eight. The CO2 drop checker started turning yellow which indicates that the CO2 levels are too high. This makes sense since the aquarium is still in the process of establishing and equalizing. The plants I recently added are also still adapting so CO2 utilization might be a little low. I reduced the bubbles per second to two and will wait and see.
