Hey All, Just wanted to share a quick note about a change I made to my CO2 system. I wasn't very happy with the amount of CO2 that was bubbling out of my tank without being absorbed, so I tried changing it up a bit today. I have a filter setup that returns the water to the tank down a vertical tube. I drilled a small hole in the lowest part that is under water and squeezed the CO2 line through it. It seems like things are much more efficient now. The bubbles go up in the returning water line, but don't have any way to escape, so they're just bouncing around until the water absorbs them. I'm not seeing any bubbles at all rising to the surface anymore and I didn't even have to buy a fancy reactor.
