CO2 issues, almost killed fish
I set up a DIY co2 system in my fluval edge 6gal. It appeared to be working well, the hose was plugged with a piece of felt to make small bubbles, and then it was jammed into the filter intake.
After a couple of hours, my fish were all gasping at the top of the water. I did a fast 60-70% water change and uncapped the co2.
For the 2L soda bottle I just used 1 pack of yeast, about 2 cups of sugar and water. Do I have too much yeast in there?
I wanna get this co2 working, and I dont want to kill my fish.
