Sealing DIY CO2 Generators I have used old juice jugs used as CO2 generators for two of my tanks and I've always struggled to seal the tubing into the hole in the lid. I tried using hot glue at first, but this would crack and was inflexible and would have to be re-glued every time I moved or refilled the generators. I just bought some silicone sealant and tried this, but its much more tacky and doesn't seem to form a good seal either.
What have other people used? How do you seal DIY CO2 generators? |
