This is the CO2 "mist" vs the dissolved form of CO2 gas.
You can add the CO2 in a more active manner, blasting it through a venturi or intake of the powerhead etc.
Many do not like the bubbles(so they say, ADA does not seem to mind)
I wonder why venturi, needle wheel and other methods get such harsh criticism for that and ADA is not?
Go figure.
Many simply do not like more things in the tank.
Nice looking glassware is a trade off by making it look nice and obvious so that folks keep an eye on CO2, which is not bad, but now you have it in the tank and lots of bubbles flailing all over.
I have a few bubbles with the venturi, not much really and then have a disc as well in a 60.
I've had disc off and on over 15 years or so.
You can try it.
I'm not sure it helps or not really, vs any other form of CO2, as long as each one is used right and you get enough CO2 delivered to the plants.
The gas bubbles appear to clean plants and break up boundary layers pretty good, I've suggested the gas phase allows transfer of dissolved gases faster into submersed aquatic plant leaves.
