pressurized co2 confusion
I am setting up a new planted tank, my first serious attemp at it really. I am going to do a pressuried co2 system, I have a miluwakee something or other pressure gague that attatches to the tank and has a bubble counter and all that cool stuff, but am confused about 1 thing in particular. When I connect the tubing to my reactor, which will be DIY inline on the drain from my tank, what keeps water from filling the small c02 tube and getting to the gauge on my co2 tank. Also wouldn't connecting a tube about the size of a straw put large bubbles into the water, I thought the idea was to have small bubbles? I am confused and reluctant becuase of it, anybody care to explain?
