So, I thought my setup was awesome. I got it "right" on the first try. Made sure to teflon tape everything, tighten everything, and tested it in a bucket of water - NO leaks.
However, my first bottle emptied out in about a month. My current bottle is down to 200psi level after 2 weeks.
I did almost gas my fish twice in the last two weeks, by setting the bps to about 5-6 for 24 hours each time. But, would 48 hours of 6bps empty half the tank? The rest of the time my rate is about 1-2 bps.
I re-tested the connections again under water, and everything is solid! No leaks. The only thing I can blame now is the tubing, which I haven't tested. But, maybe it's normal to use this much, or no?
