I just found this thread
Glad to hear your homemade CO2 reactor is working good Sarah. As usual I have a few questions about your setup tho
What size bottle and amounts of yeast and sugar are you using and how long is it producing CO2? Do you just have the line running into the input of a powerhead and then chopping it into the water/tank or is it running into something else to give it more contact time? Thanks in advance
Oh here's a pic of my coralline giving off o2, I think
It reminded me of the pic you posted of your macros bubbling that I asked about
