I've had the cylinder hooked up for 4-5 weeks. I am fairly certain that there is no leaks. I think I run around 1-1.5 bubbles per second. Not totally sure but just casually counting and looking at it in the past I think that is close.
The cylinder is showing signs of being empty or getting really close to it. I have to open up my regulator valve more and more. Currently I have it wide open and nothing has came out yet. I did this same thing yesterday morning and then the co2 started coming about 5-10 minutes after I fully opened it.
How long should a 20 lb cylinder last running into a 180 gal? Am I pumping too much co2 in or do I maybe have a bigger issue?
Thank you in advance.
