I set up a CO2 scrubber this week (see picture). It pull air from the skimmer cup and supplies the skimmer pump.
You can see from the bubbles in the skimmer that it is getting air.
There is condensation in the tubes so I know that it is kept moist.
Here is what it did for my PH:
I'm getting about a 0.1 bump in PH during the night.
I was hoping to get a get a much bigger bump.
I'm using Jorgensen soda lime.
Display tank is 180g.
