A few questions for you:
- Did you shake up the bottle to dissolve the sugar?
- What are you using to diffuse the CO2
into the tank?
- How deep in the tank is your diffuser?
When I change bottle on my DIY CO2
, I usually have to give the bottle a good shake after a few hours to get the CO2
going, then shake the bottle once a week or so. I also had to raise my diffuser in the tank. I was using a piece of bamboo skewer in the end of a rigid airline at the bottom of my 29g and the CO2
pressure wasn't enough to overcome the water pressure for very long. I slanted the airline so it's about halfway down in the tank and it bubbles much more often. At the moment I have a leak in one of the caps of my CO2
bottles. It's hard to notice unless I shake up the bottle and release a lot of CO2
. The only way to tell was the top of the cap was sticky.
