THe Co2 is up and running

. I couldn't use the filter so I had to go with the ladder temporarily until I get the parts for the reactor. It seems to be working well but the bubbles are coming out pretty slowly and then bumping into each other 1/2 way up the ladder to form one big bubble.
Also one of the two liters looks dangerously close to the top whereas the other one has three inches of air between the liquid and the cap.
One thing is certain, I'm learning a lot and having fun.
