I was using this for a few weeks.
I was getting pretty good CO2
levels according to my PH readings.
As of yesterday I switched to just letting it get sprayed around the tank via the powerhead. I'm getting pearling several hours earlier than before. I swear the plants are looking better already. I can't wait to see the long term result of this method.
On the down side my tank looks like a bottle of sprite that has been shaken up and the back of the tank is a horizontally moving wall of bubbles
