I have recently set up my 54 litre (2 feet by 1 by 1) aquarium with pressurised CO2. Initially for a few days my plant load inside the tank wasn't too high but I would nevertheless leave the CO2 on with lights for the Java fern and an anubias and some freshly planted Cuba. There would be considerable CO2 bubbles floating on the surface of the water and very little pearling, if any.
I had assumed that the CO2 was not getting properly mixed in the water. I use a ceramic diffuser and position it under the spray bar.
Ever since adding more plants like HM and some crypts in the tank, the free floating bubbles on top has become a thing of the past, though everything else remains the same - bubbling rate of 2 bps and no change in diffuser position relative to the spray bar (I use an external canister filter).
Can someone please explain the science behind this to me? Does plant load have a bearing on CO2 saturation? I presume because of more plants in the system, the CO2 is now getting properly consumed and not floating on top. Is that a correct assumption?
