	need help with CO2 usage
greenfootball Fish Addict Posts: 613 Kudos: 360 Votes: 0 Registered: 23-Jul-2001	i just got my CO2 regulator set today, hooked up everything and let the output be around 1 bubble per second, but it seems like when i leave it at 1 bubble per second, after hours it gets really slow, like maybe 1 bubble every 3 seconds or so, and the output gauge drops itself from where i set it (2 kg/cm) to eventually 0, what is wrong? do i have a leak??

The needle valve was so sensitive the smallest movement made a huge difference to the rate. Seemed like I'd set it where I wanted it (fiddly) and it would kind of move slowly backwards after a few hours. What I did was - if I wanted it at say 2 bps I set it at 5 bps. It would gradually driftback again until it settled at the 2 bps rate and stayed there. This took some doing though, sometimes it would not drop enough some times too much. Once it's set learn to never touch it again Some days you're the pigeon and some days you're the statue. Remember that age and treachery will always triumph over youth and ability.

bensaf Fish Master Posts: 1978 Kudos: 1315 Registered: 08-Apr-2004	Could be the same theory - the output valve on the regulator being oversensitive adn slipping back. Some days you're the pigeon and some days you're the statue. Remember that age and treachery will always triumph over youth and ability.
