C02 System

[Branch]

For the past few years I've been running a Pro Flora C02 system in my show tank (150g). This morning I noticed the absence of bubbles in the tank and checked the cylinder to ensure it wasn't empty. On further examination I found that although the C02 was going into the regulator it wasn't coming out in to the feed pipe. Any ideas why this is happening? Cheers

Sounds like a bad regulator. Can those things get plugged up or anything?

Not sure, but not a cheap bit of kit to replace.
