Thanks for the info, Paul. I've purchased a tank and found a place to fill it (see "Where to buy & fill CO2 tanks??"), and only have a couple more questions:
1. What do the gauges measure? What sort of information can I glean from them? How do I tell when the tank is empty?
2. Other than trial and error, how do I know how much CO2 to inject? I've got about 100 gallons of water (75 gallon tank, ~25-30 gallons in sump). I figured I'd start with one bubble every second and then work up or down from there. Does this sound good?
