Drop checker and CO2 levels
I have a 30 gallon planted tank. The ph is 7.8 and the kh is 8. The drop checker solution is still blue even though my pressurized co2 system is set at 1-2 bubbles per second through an atomic diffuser. The diffuser attaches to the front glass panel where the bubbles get pushed down by the water from the filter comes down. There is a nice mist. What would increase my CO2 saturation?
